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.
