Effects of Radiation to the Human Body

Exposure to nuclear radiation regardless of the dose of the radiation is harmful to the body. Here are some of the effects of radiation exposure that you will find useful.

Arming yourself with knowledge on the effects of nuclear radiation in the human body can help you save your life and the lives of your love ones in the event of nuclear exposure.

There are two major considerations to how nuclear radiation affects the body. The first is the strength of radiation the body is exposed to and the second is the amount of time that the body is exposed.

Nuclear radiation can cause significant damage to the body’s internal chemistry. Although the body reacts by trying to repair the damaged cells and tissues, the damage caused by ionizing radiation are often too severe and therefore, beyond repair.

Radiation strength is measured in Sievert. A typical background radiation is 2 mSv/y, the Chernobyl incident which caused hundreds of fatalities reached 350 mSv/lifetime. In March 15, 2011, after the earthquake and tsunami in Japan which damaged the nuclear reactors in the Fukushima nuclear power plant, radiation levels reached 400 mSv/hour.

At moderate levels of radiation exposure the human body exhibits a range of symptoms from nausea, diarrhea, vomiting, fever and headache within hours of being exposed to the radiation. These symptoms will then vanish but will be followed after a week with new and even more serious ailments.

A person that is exposed to high levels of radiation will show the same symptoms accompanied by severe and widespread damage to the internal organs. More than half of healthy adults will be dead within a month of being exposed to high levels of radiation.

Cancer and Radiation

Research shows that the higher the dose of radiation that the body is exposed to, the higher the risk of developing various types of cancer. However, even a small dose of radiation exposure drastically increases the risk of developing cancer. Exposure to 1 sievert of radiation increases the chance of developing breast, stomach, skin and lung cancer by 5 percent.

The bone marrow and the thyroid gland are especially vulnerable to radiation. Leukemia, a form of cancer which comes from the bone marrow, is one of the most common effects of exposure to nuclear radiation.

Long Term Effects

Perhaps, one of the most damaging effects of radiation exposure is genetic mutation. As the body tries to repair the cells damaged by the ionizing radiation, there is a great risk that the repair process itself is flawed. This result to genetic mutation which can cause physical deformities and learning disabilities that can be passed along from generations to generations.
