Act (44 U.S.C. Chapter 35). To request a copy of these requests, call
the CDC Reports Clearance Officer at (404) 371-5976 or send an e-mail
to omb@cdc.gov. Send written comments to CDC Desk Officer, Office of
Management and Budget, Washington, DC via fax to (202) 395-6974.
Written comments should be received within 30 days of this notice.
Proposed Project
Assessment of Occupational Exposures to Electric and Magnetic
Fields (EMF)--New--National Institute for Occupational Safety and
Health (NIOSH), Centers for Disease Control and Prevention (CDC).
This proposal is to conduct a validation study on an interview-
based procedure for assessing occupational exposures to electric and
magnetic fields (EMF) from AC electricity. Participants in the study
will be asked to wear specially designed instruments to measure a range
of EMF that employees encounter as part of their daily work practices.
These devices have been field-tested and meet all safety requirements.
This study will capture not only the magnetic field magnitude but also
its frequencies, induced currents and contact currents. This study will
provide important new information that will shed light on EMF and
health effects on workers.
This study has the following objectives: (1) Validate an interview-
based EMF exposure assessment algorithm against measurements of the
time-weighted average (TWA) magnetic field magnitude used in previous
epidemiologic studies, (2) calibrate the parameters in the algorithm in
order to improve the exposure estimates, and (3) determine the
correlation between the EMF exposures from the algorithm and
biologically-based metrics measured by new instrumentation. These
biologically-based metrics consist of either characteristics of the
magnetic field that have produced biological effects in laboratory
studies or currents in the body resulting from contact with charged
surfaces. For the higher correlations with the TWA magnetic field
magnitude, these data will be used to determine whether the exposure
algorithm can be modified to accurately assess exposures to the
biologically-based metrics.
This is a one-time study of workers of an electric utility in
Canada and a Federal research laboratory in the U.S. There will be no
cost to respondents except for their time.
