Radioactive Contamination Flashcards
1
Q
When is an object contaminated?
A
If it contains radioactive nuclei, which will go on to decay and release ionising radiation
2
Q
What changes the way contaminated items are dealt with?
A
Amount of contamination present
Type of radiation emitted
The half life of the radioactive substance present
3
Q
What is irradiation?
A
The process of exposing an object to ionising radiation
4
Q
What irradiation can make an object radioactive?
A
Neutron only
5
Q
How can you minimise level of irradiation?
A
Minimise exposure time
Maximise distance from source
Use appropriate absorbers (shielding)
6
Q
What is an example of irradiation can be useful?
A
Gamma rays can be used to sterilise food and medical tools
