ELFJEM

ELF Magnetic Field Job-Exposure Matrix - developed within the framework of the INTEROCC study.
The INTEROCC study started with a JEM by Bowman et al. (J Occup Environ Hyg 2007;4:715-28.), and made two major changes:

  1. Re-coding the data from U.S. job codes to the ISCO 1988 codes (with some electrical occupations coded to the more-detailed ISCO 1968 codes).
  2. Adding additional data, especially for INTEROCC occupations and countries that were missing from the 2007 JEM. 
This ELF-JEM was used in the following manuscript: Turner MC, Benke G, Bowman JD, Figuerola J, Fleming S, Hours M, Kincl L, Krewski D, McLean D, Parent ME, Richardson L, Sadetzki S, Schlaefer K, Schlehofer B, Schuz J, Siemiatycki J, van Tongeren M, Cardis E. 2014. Occupational exposure to extremely low frequency magnetic fields and brain tumor risks in the INTEROCC study.
