Resumen inglés	A method is presented to compute the activity of a radioactive source. The principle of the method is based on the tuning of b, the time constant of the RC circuit of the detector with l being the rate of emission of the source, using a statistical argument. The stochastical process involved refers to the distribution of the following random voltage: Vt = ∑(0 < ti ≤ t) Yi c-b(t - ti) where the ti are Poisson dates of emission and the Yi are random or deterministic pulse heights. The case of Yi gamma distributed is investigated. This method could replace a crude counting for the case of a very intense source where this kind of measurement would be delicate due to the problem of rapid data acquisition.
