THE METHOD OF INDICATING RADIOACTIVITY PERCENTAGE RATIOS COMPRISING THE STEPS OF PRODUCING ELECTRICAL PULSES PROPORTIONAL IN RATE OF OCCURRENCE TO THE STRENGTH OF A FIRST RADIOACTIVITY FIELD, SCALING THE PULSES BY A DECIMAL FACTOR OVER A PRESET TIME INTERVAL WHILE REGISTERING THE NUMBER OF PULSES PRODUCED BY SUCH SCALING AND THE PRODUCING ELECTRICAL PULSES IDENTICALLY PROPORTIONAL IN RATE OF OCCURENCE TO THE STRENGHT OF A SECOND RADIOACTIVITY FIELD, AND SCALING THESE PULSES OVER THE SAME TIME INTERVAL BY A FACTOR EQUAL TO THE NUMBER SO PREVIOUSLY REGISTERED, WHILE REGISTERING THE NUMBER OF PULSES PRODUCED BY SUCH LATTER SCALING, WHEREBY THE LATTER REGISTERING CONSTITUTES A DIRECT INDICATION OF THE PERCENTAGE RATIO OF THE STRENGTH OF THE SECOND FIELD TO THAT OF THE FIRST.
