Dosimeters measuring radiation

Updated on September 19, 2014

Measuring Radiation. Dosimeter device

Radiation awareness is a very important topic. With the nuclear disaster in Japan the world is more conscious about the nuclear energy we use and the drastic fear of meltdowns and and the fact that radiation can truly effect the world's population health. As I watch the news I realized that many reporters reporting from Japan where using a personal device that detects how much radiation they have been exposed to called Dosimeters, and I decided to do a little more research o the device so I could share with you. These devices are great since they help measure and detect how much radiation a person has been exposed since they were wearing the device and it can be a life saver for those close to effected areas.

The effects of Radiation on Human Body

As according to the effects of radiation on the human body are:

(1) Hair: The losing of hair quickly and in clumps occurs with radiation exposure at 200 rems or higher.

(2) Brain: Since brain cells do not reproduce, they won't be damaged directly unless the exposure is 5,000 rems or greater. Like the heart, radiation kills nerve cells and small blood vessels, and can cause seizures and immediate death.

(3) Thyroid: The certain body parts are more specifically affected by exposure to different types of radiation sources. The thyroid gland is susceptible to radioactive iodine. In sufficient amounts, radioactive iodine can destroy all or part of the thyroid. By taking potassium iodide, one can reduce the effects of exposure.

(4) Blood System: When a person is exposed to around 100 rems, the blood's lymphocyte cell count will be reduced, leaving the victim more susceptible to infection. This is often refered to as mild radiation sickness. Early symptoms of radiation sickness mimic those of flu and may go unnoticed unless a blood count is done.According to data from Hiroshima and Nagaski, show that symptoms may persist for up to 10 years and may also have an increased long-term risk for leukemia and lymphoma.

(5) Heart: Intense exposure to radioactive material at 1,000 to 5,000 rems would do immediate damage to small blood vessels and probably cause heart failure and death directly.

(6) Gastrointestinal Tract: Radiation damage to the intestinal tract lining will cause nausea, bloody vomiting and diarrhea. This is occurs when the victim's exposure is 200 rems or more. The radiation will begin to destroy the cells in the body that divide rapidly. These including blood, GI tract, reproductive and hair cells, and harms their DNA and RNA of surviving cells.

(7) Reproductive Tract: Because reproductive tract cells divide rapidly, these areas of the body can be damaged at rem levels as low as 200. Long-term, some radiation sickness victims will become sterile.

Day to Day Radiation Exposure

Common source of radiation exposure that we all are exposed to on our daily lives.

1 Medical procedures: such as x-rays, mammograms and nuclear medicine

2 Radioactive Foods: Banana, carrots, white potatoes, lima means and all organic foods contains a small amount of radiation from its potassium.
