      <subfield code="a">The objective of this study is to investigate how closely the variables of exposures to magnetic fields based on the last job held in an electrical utility in Québec, Canada, compared with those based on the workers'entire employment history with the company. The resulsts indicated some loss of information when estimates of exposure were based on the last job only</subfield>
