“The Law on Radiation Safety of the Population” and regulations for individual radiation-dosimetry monitoring suppose separate registration of background and technogenic exposure components. Background and technogenic radiation levels are comparable in the conditions of accident-free work of the personnel of group B and for the population. If their measurements are made by the same type of devices, there is a computational problem of background subtraction, which is usually solved by arithmetic methods, or even ignored. This leads to a known paradoxical bias of dosimetric information, allowing the existence of negative dose estimates or negative activities. The way allowing to overcome this paradox is considered in the publication.
