Exposure of school employees to extremely low frequency magnetic fields.
This study was initiated to determine and compare daily occupational exposure (OE) and non-occupational exposure (NOE) of three employee groups of teachers, maintenance workers and secretarial staff in a Canadian school district. The time-weighted average (TWA) individual OE for subjects ranged from 0.4-3.8 milligauss (mG), and the TWA NOE ranged from 0.2-7.1 mG. TWA OE and NOE were 1.2 mG and ...
