At the initial moment the activity of a certain radionuclie totalled 650 particles per minute.What will be the activity of the preperation after half its half-life period? |
|
Answer» Solution :The ACTIVITY is proprotional to the number to the number of parent nuclei(assuming that the daughter is not radioactive). In half its half-life period, the number of parent nucli decrease by a factor `(2)^(-1//2)=(1)/(SQRT(2))` So activity decreases to `(650)/(sqrt(2))= 460` particles per minute. |
