The incorporation of radioactive substances

The incorporation of radioactive substances is getting them into the body through the gastrointestinal tract, lungs, skin and others) in the process of human activity (with food, water, air), in production when working with radioactive substances, certain forms of treatment (for example, radon baths and others), radioisotope diagnostics, as well as for testing and use of nuclear weapons.
The incorporation of radioactive substances creates internal exposure (see) of the body (relative to the uniform or mainly bones, reticuloendothelial system and others), which under certain conditions may cause various radiation injury (see Radiation sickness).
The degree of exposure depends on the number of incorporated radioactive substances, radioactive (half-life, mode) and physico-chemical properties (gas, water soluble compound, and so on), from their distribution within the body, to the degree and nature of their removing from various organs, tissues and body etc.
To accelerate the excretion of incorporated radioactive substances use of different substances forming incorporated with radioactive substances complex compounds, quickly released from the body.
