Study type: Medical/biological study (experimental study)

Increased DNA synthesis in INIT/10T1/2 cells after exposure to a 60 Hz magnetic field: a magnetic-field or a thermal effect? med./bio.

Published in: Radiat Res 1999; 151 (2): 201-208

Aim of study (acc. to author)

This study was designed to test the hypothesis that a 60 Hz magnetic field may act as a promoter of carcinogenesis in mouse fibroblasts in vitro.

Background/further details

The positive controls were tetradecanoylphorbol acetate treated cells.
