4.4.3.2 Different Half-lives of Radioactive Isotopes Flashcards
1
Q
What do radioactive isotopes have?
A
radioactive isotopes have a very wide range of half-life values
2
Q
Hazards of radioactive material with short half-life:
A
- source presents less of a risk - does not remain strongly radioactive
- initially very radioactive but quickly dies down - so presents less of long-term risk
3
Q
Hazards of radioactive material with long half-life:
A
source remains weakly radioactive over long period of time
