Nuclear Radiation Hazards Guide

Friday, March 18, 2011
Responding to recent developments in Japan's nuclear crisis -following the failure of nuclear reactor cooling system in Fukushima after 9 magnitude quake-
, the World Health Organization (WHO) issued new guidelines to reduce the danger of radiation on health, especially in children and teenagers. Previously the UN also said so far the Japanese government measures to minimize the impact of radiation has the right, among others, evacuating residents within 20 km of the nuclear facilities and asked the people who live within a radius of 30 km to not leave the house.

Public within a radius of 50-100 km wear a mask in order to avoid exposure to radiation, avoid drinking tap water, always close the room and reduce out of the house. While Tokyo which is about 270 km from Fukushima nuclear power plant declared safe from radiation.

So far there has been no indication of food safety that is imported from Japan, including food products that are harvested in areas that are exposed, but crops and livestock in the area should be protected.

Here are recommendations issued by WHO:

The main radio nuclides released from nuclear power plants is radioactive cesium and radioactive iodine. Public may be exposed directly from the radionuclides from the air or food and drink contaminated by the material. Exposure to radiation can increase cancer risk.

If radio active iodine inhaled or swallowed, will settle in the thyroid gland and increase the risk of thyroid cancer. Risk can be reduced by consuming potassium iodine pills that will prevent precipitation of radioactive material. These pills must be given before or immediately after exposure to nuclear radiation. This step can reduce the risk of cancer in the long term. The use of potassium iodine tablets must be in accordance with the rules of the competent authorities.

If after exposure to radiation, you have to go into the room, remove all clothing to prevent contamination at home. Remove clothing and shoes and then store in plastic bags and then move away from your home, children and animals.

If you are asked to to be in the house,there lived in the most secure room ,with doors and windows tightly closed . Ventilation systems, such as cooling or heating system must be turned off.

Take a bath with warm water, soap and water. Report on the authorities of clothing and other personal items that may be contaminated.

Risk of thyroid cancer in person exposed to radiation is higher in the group of children and teenagers.

Avoid consuming vegetables and dairy products produced in areas near nuclear facilities could reduce radiation exposure. Food may be contaminated by radioactive material. The surface of the fruit, vegetable, or animal feed can be exposed to radiation from the air or rain water.

For the first step of prevention, vegetables and meat of cattle should be covered with plastic or tarp. Move the animal into the cage.
Radioactive can not contaminate food that is packaged well with plastic wrap or tin.

If the radiation levels are too high, it can cause flushed skin, hair loss, burns and acute radiation syndrome. Nuclear power plant workers and rescue workers may be the most exposed group than common people.

In the long term, radioactivity can also be formed in foods derived from land, river or sea water.
