Wait until the statistical error of surface beta-particles flux density
measurement results goes down to the value of not more than 10 %. Then
register five measurement results in the protocol with 5 s interval.
Calculate the average value of surface beta-particles flux density and
the main relative error of measurement.
Place the dosimeter with the open window above the 4CO source
surface, providing surface beta-particles flux density from 50000 to
100000 part./(cm
completely over the active surface of the source.
