Q
What is radioactive contamination
A
The unwanted presence of radioactive atoms on materials
2
Q
What causes the hazard in contamination
A
The decay of the contaminating atoms
3
Q
What affects the level of hazard from contamination
A
The type of radiation emitted
4
Q
What is irradiation
A
Exposure of an object to nuclear radiation
5
Q
Does an irradiated object become radioactive
A
No it does not become radioactive
6
Q
What should students be able to compare
A
The hazards of contamination and irradiation
7
Q
Why must precautions be taken during irradiation
A
To protect against hazards from the radioactive source
8
Q
Why must radiation studies be published
A
So other scientists can check the findings through peer review
