Nuclear Flashcards
1
Q
what is the decay constant
A
the probability of a nucleus decaying in the next second
2
Q
what is activity
A
decays per second (Bq)
3
Q
Why would a count rate per 1/d^2 graph not pass through the origin? Why might it curve at the end?
A
Systematic error as source & detector are not at the end of their casings
Also emitting a & B decay. Only detected when closer to the source as they have a shorter range.
