A radio active substance has a half life of 30 days. Calculate
(a) the radioactive disintegration constant (b) The average life
(c) the time taken for ¾ of the original number of atoms to disintegrate and
(d) the time taken for 1/8 of the original number of atoms to remain unchanged
Please see the attached document also.
We have, T= 30 days
(a) The radioactive disintegration constant λ = 0.693/T = 0.0231 per day (Ans)
(b) Average life Ta = 1/λ ...
Solution with detailed explanations as a word attachment. The calculations of radioactive disintegration constants are given.
