If two radioactive samples have the same activity measured in curies, will they necessarily create the same damage to a medium? Explain.

Can a radioactive sample emit all types of radiations at the same time ?

A radioactive sample S_1 having an activity of 5muCi has twice the number of nuclei as another sample S_2 which has an activity of 10muCi . The half-lives of S_1 and S_2 can be

Two radioactive samples A and B have same number of atoms initially. After 6 hours, I/8th of sample A and l/32th of sample B remains. The number of half-lives of A and B are n_(1) and n_(2) The ratio of half-lives of A and B is

Two physical quantities are having the same dimensions. Should their units be necessarily the same? Give an example supporting your answer.
