•Surveys of dielectric radio-frequency heaters were conducted at various plants throughout Canada in 1979. The heaters were used for plastic sealing and for gluing wood pieces. The devices operated at frequencies between 4 and 51 MHz and their power output ranged from 0.5 to 90 kW. The intensities of the electric and magnetic fields in the vicinity of 82 devices were measured. A significant number of the devices exposed their operators to the fields having the equivalent power density greater than 1 m W fcm 2 , and some greater than 10 m W fcm 2
