How Much Radioactivity is Too Much?
The nuclear accident released radioactive cesium-137 and iodine-131.
What is radioactive cesium-137?
It is absorbed by the green parts of the plants directly or through the roots. It is also found in milk, meat and fish via this detour. Mushrooms were particularly polluted after the Chernobyl disaster. High levels of cesium-137 can damage human muscle tissue and kidneys. It is distributed evenly in the body so that its radiation hits the whole organism. Cesium 137 decays with a half-life of 30 years - that is the period of time that passes until half of the radioactivity is broken down.
What is radioactive iodine 131?
The radioactive iodine isotope 131 is created during nuclear fission in a nuclear reactor or during a nuclear weapon explosion. This substance accumulates in the thyroid gland when it enters the environment and is absorbed by humans. It is a very volatile substance that can be transported quickly over long distances in the air. In the first weeks after Chernobyl, iodine 131 was the main source of food contamination. It is mainly consumed with fresh milk.
What to do if a radioactive cloud comes?
- Under no circumstances should children play outside.
- It is important to wash thoroughly and change clothes after each time you are outdoors.
- Food such as garden fruits, which could be contaminated, should be avoided.
What to do if there is a threat of radioactive contamination?
- Residents should wear breathing masks or other filter masks to prevent the body from absorbing radioactivity.
- Protective clothing can help, such as waterproof rainwear. It can't keep the rays out - only a special material with lead could do that - but it prevents contaminated particles from settling on the skin.
- Potassium iodide tablets (iodine tablets) taken in good time prevent radioactive iodine ingested through respiration from accumulating in the thyroid gland.
