Abstract

Calibrating electrometer by a solution of radium salt takes more steps of operation which have to be repeated at least three times.It will take at least three days.For a quick and exact calibration, a new method is provided.By this method the instrument can be put into use as soon as it has been calibrated and a process which deals with waste solution of radioactivity can be avoided.
Finally, we have advanced a 'radon equivalent' orineiple accoreing to the equivalent current of ionization, and a new comparison measurement is established.
