Dosimeter "Bella", as a typical "Postchernobyl" consumer appliance.
Before "Chernobyl", such concept as consumer dosimeter simply did not exist. Radiation measurement was an exclusive prerogative of experts- atomic scientists and military men. But the life has introduced the corrective amendments and after spring of 1986 the Soviet radio instrument-making industry has rushed to satisfy, unexpectedly appeared, mad demand for consumer dosimeters.
The ten years period from 1986 on 1996 was, without any doubt, a heyday of consumer radiometers.
