Environmental Health

The harmful effects of nuclear weapons get much coverage for their death and destruction, but the waste from radioactive generation often gets overlooked. Radioactive waste leaks radiation like...

Science has known about the existence of gamma radiation for over 100 years. Gamma radiation poses all of the same health risks that other high energy radiation, like X-rays, cause. Negative...

Low levels of radiation may kill or damage insignificant numbers of cells in the body, which will be replaced through normal growth cycles. High dosages of radiation, however, kill large portions...

Sunlight, natural minerals and natural gases all emit low doses of radiation every day. The human body is designed to be a self-repairing system that can stand up against these natural elements....

Radiation is a natural element in the physical world. All living organisms require some form of radioactive energy to remain alive. These energies become damaging when the atoms contained inside...

Every day of our lives we are exposed to radiation. The majority of this radiation comes from natural sources---approximately 82 percent according to the Nuclear Regulatory Commission---and comes...

Iodine 131 is a radioactive version of iodine that is created during nuclear reactions. It can be harmful to people who are exposed to high doses of it. It is radioactive for only a short period...

A light, short-range particle discovered in the 1900s by Henri Becquerel that emits fast radiation during radioactive decay and has the ability to penetrate deep into the human skin is called beta...

Acute radiation exposure (leading to acute radiation syndrome) involves full-body exposure to a high dose of radiation within a short period of time. Acute radiation sickness can be fatal, but in...

Radiation is energy that travels through space. Non-ionizing radiation is as common as visible light, but encompasses UV, microwave, RF and infrared sources. There are risks with these but even...

Pollution has negative effects on human health. The effects will depend on the type of pollutant and how it is delivered. Solid waste, such as garbage or other waste that is thrown in to a...

We must all be careful to guard ourselves from UV (ultraviolet) radiation. Especially during the summer months.

Radiation occurs when the unstable nuclei in atoms decompose. The particles they release are radiation. There are different types of radiation, depending on the type of particles released. In...

Most of us enjoy getting a good tan from time to time, and since summer is only few months long, some go to tanning salons to stay bronze throughout the year. We like the relaxation and how it...

Adverse effects due to microwave radiation from cellular phones, radio transmission and radar traffic devices are topics of controversy and ongoing research, according to the United States...

The increased use of cell phones has brought about serious concerns regarding the probable health hazards. This is because mobile phones use electromagnetic radiation in the microwave range....

EMF radiation is all around us because our modern lives include electricity. Computers, cell phones, microwave ovens and cordless phones all emit EMF radiation. This radiation lowers our melatonin...
