The disintegration rate of a certain radioactive sample at any instant is `4750` disintegrations per minute. Five minutes later the rate becomes `2700` per minute. Calculate
(a) decay constant and (b) half-life of the sample

The disntergration rate of a certain radioactive sample at any instant is 4750 dp m . Five minute later, the rate becomes 2700 dp m Calculate half-line of sample.

The disintegrationn rate of a certain radioactive sample at any instant is 4750 dpm which becomes 2700 dpm 5 min later. Calculate the half life to sample?

A counter rate meter is used ot measure the activity of radioactive sample. At a certain instant the count rate was recorded as 475 counters per minute. Five minutes later, the count rate recorded was 270 counts per minute. Calculate the decay constant and half life period of the sample.

The rate of disintegration of a radioactive sample can be increased by :-

A counter rate metre is used to measure the activity of a radioactive sample. At a certain instant, the count rate was recorded as 400 counters per minute. Five minutes later, the count recorded was 200 counts per min. Calculate the decay and half-period of the sample.

A radioactive sample at any instant has its disintegration ratye 5000 disintegrations per minute After 5 minutes , the rate is 1250 disintegration per Then , the decay constant (per minute)

The rate of disintegration of a certain radioactive sample at any instant is 8100 dpm. Fifty minutes later the rate becomes 2700 dpm. The half of the radioactive sample will be (Take log2=0.3, log3=0.5, log5=0.7 )

For a given sample, the countring rate is 47.5alpha particle per minute. After 5 times, the count is reduced to 27 alpha particles per minute. Find the decay constant and half life of the sample.
