A radio receiver, such as a pocket radio or car stereo, puts out negligible amounts of radiation in the form of electric fields. How much radiation it produces depends on two factors: the design and the receiver circuit's power consumption. A transmitter puts out radio energy by design; its power is far higher than a receiver's, but in both cases the radiation is not harmful.
If you're a chemotherapy patient, there are a few important exercises that you're going to want to learn more about. Get tips on exercises for chemotherapy patients with help from a celebrity peak performance coach and fitness minister in this free video clip.
The power of pink is a message that should extend far beyond October, which is Breast Cancer Awareness month. As we move away from the pink balloons, T-shirts and slogans, we need to continue to be aware of our own bodies, as education is key to survival. As for the breast cancer survivors, those who are still fighting and the women who have lost their battles, their stories should continue to be told. By sharing these women’s stories, getting educated and talking about what breast cancer awareness really means, we keep hope alive and inspire others to keep fighting.
When X-ray light passes through any object, the object's properties influence the light. This is especially true in X-ray technology, or radiography. When technicians send X-ray light, or gamma rays, through your body, the rays also move through intensifying screens contained in the X-ray film cartridge. Intensifying screens are meant to enhance the visibility of the organisms being assessed, while (in varying degrees) darkening everything else. Intensifying screens influence the density, or visual integrity, of X-ray images.
EMF (Electromagnetic Field) radiation surrounds us constantly. From simple electronic devices such as computers and cellphones to high-voltage power lines overhead, we are bathed in a sea of subtle magnetic frequencies. Some claim that the government has been performing experiments upon its own people using radiation. While many might place this topic squarely in the realm of conspiracy theory, the truth is a bit more complex than could be addressed by fearful fanatics or fluff news articles.
According to the Keep America Beautiful (KAB) organization, more than 51 billion pieces of litter land on roadways across the United States every year. In addition to monumental cleanup costs, this pileup of litter harms the environment, including the earth's natural resources and ecosystems.
The multileaf collimator (MLC) was first used in alloy block field shaping. However, it has since been widely applied to important clinical functions such as the dose delivery of radiation therapy for cancer patients. The average MLC contains between 40 and 120 leaves that block radiation beams from reaching healthy tissue. Produced by several manufacturers, the MLC consists of three configuration types: upper jaw replacement, lower jaw replacement, and tertiary level. Each has its own benefits and drawbacks.
Extended exposure to loud noise can degrade a person's hearing over time. For employees in loud working environments exposure to occupational hearing loss is a real risk. The Occupational Safety and Health Administration has mandated hearing conservation programs administered by employers who subject employees to a time-weighted average of 90 decibels or more in an 8-hour shift. Calculation of occupational noise exposure is done by taking direct measurements using a sound-level meter and using a mathematical equation to determine noise dosage. The dosage can be used to determine an employee's time-weighted average to occupational noise exposure through the use of…
Uranium is a naturally-occurring radioactive element found in rocks, soil, air and plants on the planet. Throughout the country, uranium is commonly found in drinking water that comes from wells. There are certain health concerns with ingesting significant quantities of uranium that you should be aware of if you are in an area where it is commonly found in drinking water.
A seroma is a tumor-like collection of fluid that occurs at a surgical site or after trauma. They are formed by an accumulation of lymph, which is a fluid made in part of white blood cells. They are a normal part of your bodies healing process, and small seromas form after all surgical incisions. They appear as lumps filled with yellow or white fluid, and are not a life-threatening condition by themselves. They become a problem when the fluid continues to collect, often resulting in pain and the threat of infection. At this point, medical intervention is necessary. Though there…
Nits are tiny eggs that female lice lay at the base of hair shafts. Because they are so small, nits can easily be mistaken for dandruff or residue from hair products. The difference is that a nit will be firmly glued to the hair shaft, making it difficult to remove. In order to determine whether a nit is alive or has already hatched, you will need to use a magnifying glass.
Radiographic cassettes are the plastic covers that hold X-ray film. Starting around 1948 the cassette was tweaked and improved upon in order to find the best combination of absorption time and clearest captured images. In the earliest days a person would stay exposed to the X-rays for 11 minutes, but now it takes mere milliseconds, which is about 2 percent of the overall exposure time from before.
All of us are exposed to radiation each day. Our natural world is made up of tiny particles called atoms. Atoms can either be radioactive or nonradioactive. Radioactive atoms give off radiation. When discussing health risks, radiation is broken down into two categories: ionized and non-ionized. Ionized radiation has a high energy level. It can alter the chemical make-up of atoms and change the DNA cells of people. Non-ionized radiation has a lower energy level. This lower energy level does not alter atoms or damage human DNA. The chemical process of an atom changing into ionized radiation particles is called…
Earbuds are inner ear headphones commonly associated with MP3 players and modern listening devices. Listening to earbuds at high decibels for long periods of time can cause hearing damage. The cochlea, a snail-shaped space within the inner ear contains 16,000 hair cells, which vibrate, activating nerves that translate sound. Damage to this area is irreversible as these tiny cells can die off due to loud noises.
Obstetrics is a field of medicine that specializes in the female reproductive system, pregnancy and postnatal care. Doctors normally provide obstetric care; however, certified nurse midwives also practice in this area. Obstetricians are lifesavers. In fact, a town in rural northern Japan was so desperate for obstetricians that it promised a horse to any obstetrician willing to go there. The field of obstetrics encompasses several different topics or focus areas.
Radiographic exposure factors determine the visibility of the anatomic structures on an X-ray. They also affect patient radiation dose. Although most digital X-ray systems provide the ability to manipulate the amount of blackness or various shades of gray on an X-ray after it has already been processed, administering an acceptable amount of exposure to the patient remains a priority. The X-ray operator, rather than a computer, should be responsible for radiation exposure and film quality.
Super hydration is a method of detoxification, practiced by drinking a gallon of ice-cold water a day. According to its proponents, super hydration is a perfectly healthy and effective way to expedite fat loss and to build muscle. Warmed or room temperature water will not lead to the same results, but by sticking to a clear and simple method, super hydration can very well yield immediate nutritional gain, leading to an overall healthier lifestyle.
The human body can be home to many different types of organism, from the microscopic to parasites that can be seen by the naked eye. The organisms that cause disease may normally live on or in the body, or they may infect the body at some point and stay alive for years.
Electric magnetic fields are present throughout the modern world; they are found in any area where electricity is generated, transported or electrical equipment is used. The effects of EMFs can be seen on other electrical equipment and some scientists and researchers claim on human health.
In action movies, the bad guy presses the button, the bomb erupts, and the good guy gets catapulted through the air, landing about 30 feet away. Flames leap high in the air, and the good guy manages to get up and keep walking. This is classic Hollywood imagery, but complete fiction. When actual bombs go off, there is almost no flame, but rather a burst, and much more substantial damage done to people nearby.
Diffusion is defined as the passive movement of a solution from an area of higher concentration to an area of lower concentration. This process is used extensively in cells of all organisms to move nutrients, ions and waste material into and out of the cell. The diffusion of water, in particular, is called osmosis and is of utmost importance in plant cells as it is utilized by organelles to maintain the plant's rigidity and structure. This process depends upon solute concentrations inside and outside of the cell and can be detrimental to the plant's health.
Uranium is a metallic element that emits radioactivity; it is a key component in nuclear weapons and nuclear reactors. Uranium occurs naturally in the earth and has been causing health problems in miners since as early as the 14th century. Uranium mining remains highly hazardous, presenting the risk of increased rates of lung cancer for miners if precautions are not taken.
An explosion is a sudden release of energy accompanied by radical changes in pressure, loud noise and possibly a flash of light. It may be caused by natural events, such as the buildup of gases in a mine, or deliberately artificial ones, such as nuclear fission. Explosions have both mechanical and chemical effects to which the human body is subject. Human injuries from explosions can be divided into many categories.
The healing elements or properties of herbs are classified according to functional use. Herbs are prepared as tinctures, compresses, poultice, teas and infusions. They can also be added to salves and some can be eaten fresh or lightly steamed. It is always important to consult with a local herbalist about the safety of locally grown herbs.
Charity walks are group walks to raise money for different charities. Many charity organizations have annual walks to raise money for their causes. Charity walk participants walk a set distance or route and typically have sponsors who agree to give a specific amount to the charity for the participant they are sponsoring.
UV radiation is a consequence of exposure to the sun or to sun lamps. While exposure to sunlight is necessary to both animal and plant survival, overexposure to sunlight can have detrimental effects on both plant and animal life. Most of the effects of overexposure are permanent and can be treated but may not be able to be completely cured.
Radiation exposure is a topic that can evoke feelings of fear and anxiety. Movie and television depictions often paint a dark picture but may represent only part of the story. People are subjected to many natural sources of radiation. Although it isn't necessary to fear all radiation, it's important to have respect for its destructive properties. It's also helpful to understand some of the factors affecting radiation exposure. Minimize the amount of time you are exposed to it and increase your distance from its source.
Cellular differentiation is the process by which the subsequent divisions of a single fertilized egg cell develop into the many specialized cells found within a mature organism. A totipotent cell can differentiate into all cell types, while a pluripotent cell can differentiate into only some different cell types. Pluripotent mammalian cells are known as stem cells. The only totipotent mammalian cells are the zygote and early embryonic cells, while the cells of many other species can revert to totipotency.
Computers serve as a quick and convenient way to get things done. For example, you easily can do everything from typing documents, designing slide shows and presentations, to creating your own music or art. You also can access useful information and media on the Internet. For these reasons people rely heavily on computers, especially at places like offices, schools, hospitals and at home. Unfortunately, using computers can also bring many negative effects for your overall health.
Patients undergo chemo treatments, also known as chemotherapy, to treat their cancer. You can receive treatment in your own home, the hospital, your doctor's office or a clinic. Patients undergo different applications and lengths of chemo treatment. These drug also cause some side effects.
Chemotherapy provides life-saving chemicals to kill growing cancer cells in your body. You can take chemotherapeutic drugs orally, have chemotherapy creams applied directly to affected areas or take it through an intravenous line. Depending on your treatment regimen, you may receive chemotherapy at your doctor's office, in a hospital setting or at home. If you don't take chemo orally, you can expect to spend some quality time at your doctor's office or in the hospital. Chemo treatments can average between one or more hours. To help pass the time, provide yourself with activities to keep busy.
Allium cepa is the scientific name for red onion bulbs. The respiration rates of these bulbs can be affected by radiation. These rates affect the quality of the bulbs during storage.
Race for the Cure events to raise money for breast cancer research have been taking place for more than 25 years and are organized nationwide by Susan G. Komen for the Cure. Between 1982 and 2010, this nonprofit organization raised $1.5 billion for breast cancer research. From the time her cancer was diagnosed, Komen spent her time trying to find ways to improve the lives of other women with breast cancer. When she died, her sister Nancy Brinker picked up the fight and founded the organization. Taking part in a Race for the Cure event is one of several ways…
PCV, the name for a triple-drug cocktail used to treat brain tumors, is an abbreviation of the combined names of the chemotherapy drugs procarbazine, lomustine (also known as CCNU) and vincristine. According to the National Center for Biotechnology Information, doctors conducted studies using PCV therapy on two groups of patients: the first consisted of 16 adults with newly diagnosed brain tumors, and the second consisted of five adults with recurring, low-grade brain tumors. Three out of five patients with recurrent tumors responded to PCV treatment, while 13 of the 16 newly diagnosed patients showed evidence of response, according to the…
Chemotherapy (drug therapy) is often used to destroy cancer cells. When chemotherapy follows another treatment, such as surgery, it is known as adjuvant chemotherapy. Folfox is commonly used as an adjuvant treatment for bowel cancers.
Obstetrics has made slow but significant advances since its birth. Each gradual step was carefully planned to save the lives of women and actively continues today for the same cause.
MLS stands for myxoid liposarcoma, the second most common type of liposarcoma. This type of tumor is usually found in the leg and is made of mostly fat cells.
If moodiness interferes with your ability to deal with daily tasks and smoothly interact with people around you, you'll want to investigate ways to overcome your emotional swings. Many people opt for herbal remedies that are readily available without a prescription. Most of these remedies are relatively inexpensive, and some can be self-prescribed after a little research. However, take the time to make sure you are taking the right herb for you.
Professional nursing certification and licensing requires a nurse to obtain continuing education units (CEUs). One area a nurse may receive continuing education credits in is chemotherapy.
Chemotherapy is the use of drugs to fight cancer cells while reducing the side effects of the treatment to a minimum. It may not always be effective. In fighting a brain tumor, for instance, not all drugs can pass through the brain's protective barrier that allows molecules to reach the central nervous system. Alternative delivery methods for chemotherapy recognize that the choice of drugs as well as the delivery method influence success of the treatment.
High-dose chemotherapy, because it destroys normal cells as well as cancer cells, has a wide range of side effects. Counseling gives advice to patients suffering bothersome minor symptoms, from loss of appetite to dry mouth, hair loss and mouth sores. More serious symptoms, such as chronic diarrhea and sleeplessness, often require medication, and radiation therapy can also be necessary if cancer cells persist. The Aptium Oncology Research Network is investigating whether acupuncture relieves chronic fatigue after chemotherapy.
There are many signs and side effects of chemotherapy. It is important to remember that everybody reacts differently to the treatment, and there is no sure way to predict what the signs of chemotherapy will be. Below you will find some of the more commonly reported signs of the therapy and ways that may help to alleviate some of these symptoms. Keep in mind that these signs and symptoms do not tell you if the treatment is or is not working; only your doctor can determine that.
Chemotherapy is an exhausting and draining experience for a cancer patient. Gifts should help enhance the patient's comfort and support his recovery. Chemotherapy patients often experience fatigue, nausea, hair loss and a suppressed immune system. Familiarity with the side effects of chemotherapy and struggles of cancer can help identify useful gifts for someone suffering from cancer.
Ozonators are appliances that generate ozone gas (O3) for purifying water and air in the home and in industrial settings. Most units operate simply by drawing air inside where it is exposed to the radiation of an ultraviolet bulb, then discharging it into room air or into water.
Stents keep narrow or blocked arteries open so that blood flow restores, improving arterial viability and health. They also provide an avenue for physicians to route medication into the cancer patient's system.
Chemotherapy treatment uses a variety of chemical agents directed at killing cancerous cells in your body. This therapy involves taking a variety of drugs at specific intervals while under medical observation in a medical facility. Frequency of treatments range from every day to every few months. In addition to the cancerous cells, your gastrointestinal tract, immune system and scalp all suffer significantly during chemotherapy treatments. Several strategies ease the discomfort of these side effects during your treatments.
Efudex, generically known as fluorouracil, is a topical cream used for the treatment of solar or multiple actinic keratoses, which are rough-textured lesions that form on the outermost layer of the skin after years of exposure to ultraviolet light, such as sunlight. Efudex is also indicated for superficial basal cell carcinoma when other treatments have not worked. Efudex is thought to work by killing rapidly dividing cells such as those present in carcinomas and keratosis. While using Efudex, the skin will progress through several stages, at times appearing worse than when treatment was first started. It is important to continue…
Pontine glioma is high-grade cancerous tumor located in the lowest stem of the brain. Although this type of tumor is most prevalent in children, about 2.4 percent of intracranial tumors in adults are pontine glioma.
Germicidal lamps are used in applications to purify water and air. A number of brands produce these lamps in a number of configurations. Lamps are available that use bulbs that are U-shaped, have a bi-pin, single pin, four-pin, screw in or several other bulb base configurations. Some lamps are designed to also generate ozone. These lamps are used in water purification or to help eliminate odor from the air. All lamps should produce 254 nanometers of ultraviolet radiation to be effective in germicidal applications. Ozone generating lamps should be able to produce an additional 185 nanometers. All lamps and bulbs…
Getting rid of nits can be a time-consuming and frustrating process. They used to be relatively simple to get rid of using shampoo treatments. Unfortunately, nits and head lice have built up a resistance to these products, so they're not always all killed. To ensure you don't get a re-infestation, it's important to make sure all the nits are dead after a treatment. It only takes one nit to mature and lay more eggs to start off the whole process again, so check after every treatment.
