Study type: Medical/biological study (experimental study)

Possible associations between ELF electromagnetic fields, DNA damage response processes and childhood leukaemia. med./bio.

Published in: Br J Cancer 2003; 88 (12): 1939-1941

Aim of study (acc. to author)

To verify the hypothesis that extremely low frequency electromagnetic fields may possess copromoting potential for leukaemia.

Background/further details

A blood sample of a healthy 46 years female donor was devided into four groups: 1) control group, 2.) gamma radiation at 2 Gy, 3.) exposure to electromagnetic field alone, 4.) co-exposure (gamma radiation at 2 Gy plus electromagnetic field exposure).

Exposure 1: 50 Hz
Exposure duration: continuous for 12 h

Methods Endpoint/measurement parameters/methodology

Investigated system:
Time of investigation:
  • after exposure

Main outcome of study (acc. to author)

The data from 12 hours post gamma radiation exposure to electromagnetic fields of different magnetic flux densities provide no support of the hypothesis that electromagnetic field may have influence on response to gamma radiation induced DNA damage in human lymphocytes.
