Radiaito Flashcards
1
Q
Only decay that reduces mass number is
A
Alpha decay
2
Q
Beta minus decay
A
Makes neutron to proton increases proton number
And it relaxes an electron to conserve charge
3
Q
Half life full definition
A
The half life is the AVERAGE TIME IT TAKES FOR HALF THE NUMBER OF NUCLEI TI DECAY
4
Q
Activity
A
Is the rate of decay, decays per second
So 2000 bq from alpha source means 2000 decays in a second = 2000 alpha decay
5
Q
What is the decay constant
A
The probably if decay of an inducuial nucleus per unit time
6
Q
Equation for activity decay constant and number of nucleus
A
A= Decay constant x N
