Someone verify this please (this is very much in the syllabus )
Background radiations can be detected by Geiger counter and its rate constant at a given place.First record the background radiation by Geiger counter. Let count rate be n .Now, count the emission rate from the given radioactive source . Let the count rate be N
Therefore, True rate of emission = N - n |
