The exposure room was lined with 0.9 mm thick aluminum (double layer for walls near the benches). Ambient temperature and relative humidity in the exposure room was maintained at 21°C and 50%, respectively.
Setup
Mice housed in cages, containing no metal parts, which were placed on wooden benches on which the coils were fitted. The cages were rotated daily.
Additional info
The control bench was shielded with 0.9 mm thick aluminium on all four sides to a height of 1500 mm above the floor (700 mm above the bench) but no shielding was placed over the bench to avoid affecting the lightning and temperature of the control animals. The average air temperature were 21°C, 23°C, 23.5°C and 24°C for control, low field, medium field and high field benches.
These investigations failed to demonstrate any health effects that can be clearly related to the magnetic fieldexposure. No alterations in behaviour or indications of morbidity were detected during the initial exposure. There were no significant differences in body weight between exposed and unexposed animals at any time in the study. The clinical chemistry and hematology parameters were essentially unchanged. Although minor differences in some clinical chemistry and hematology parameters were found between control and exposure groups, the lack of exposure dependence, the lack of consistency between sexes, and the lack of correspondence with the data of the two studies all suggest that these were chance associations. Finally, all organs were normal except for isolated, generally mild, histologicallesions and lesions that were ascribed to fighting among males. There was no obvious association with field intensity.
