A Geigger Muller counter is used to study the radioactive process. In the absence of radioactive substances `A`, it counts `3` disintegration per second (dps). At the start in the presence of `A`, it records `23` dps, and after `10 m` in `13 dps`,
i. What does it count after `20 m` in ?

A Geiger melter countries is used to study , the radicuacting process in the abserence of radoactive substance A , it couts 2 disingration per second (dps) Al the start in due presence of A, it recoirds 23 dps and after 10 in 3 dps, (i) What does it count after 20 min? (ii) What is the half -life A?

The rate of decay of a radioactive element at t=0 instant 10^(3) disintegrations per second. If the half life of the elements is Is, then the rate of decay after Is will be

The radioactivity of a substance is measured in terms of disintegration per second. Then 3 xx 10^8 dps (disintegration per second) is equal to

The radioactive decay rate of a radioactive element is found to be 10^(3) disintegration per second at a certain time . If the half life of the element is one second , the decay rate after one second is?

The radioactive decay rate of a radioactive element is found to be 10^(3) disintegration per second at a cartain time . If the half life of the element is one second , the dacay rate after one second ….. And after three second is ……

Define the Activity of a radioactive sample. Write its S.I. unit. A radioactive sample has activity of 10000 disintegrations per second (dps) after 20 hours. After next 10 hours its Activity reduces to 5000 dps. Find out its half-life and initial activity.
