Radioactive contamination

is the deposition of, or presence of radioactive substances on surfaces

or within solids, liquids or gases (including the human body), where

their presence is unintended or undesirable.

Radioactive contamination can occur as a result of:

nuclear bomb improper storage of radioactive materials

leakage of nuclear installations emissions of radioactive gases as a

result of the explosion at the nuclear power plant

HOW LONG?

Duration of radioactive contamination ranging from

several hours to several weeks or even months and years.This time depends on the persistence of radioactive

elements

Methods for detection of radioactive contamination:

chemical method photographic method luminescent method

ionization method

Contaminated food is not suitable for eating, because in this way hazardous substances can be associated with the cells of the body, resulting in a greater

and longer exposure to ionizing radiation than the superficial

irradiation. It is also impossible to purify the contaminated water or food

in the home conditions.

On the contaminated area we don’t have the resources to live. All grain and

crops are dying or absorb radioactive substances themselves become a

source of radiation exposure. People and livestock from contaminated areas

subjected to less deactivation and transported outside the area

contaminated.
