Effects of 50 Hz magnetic field exposure on tumor experimental models. med./bio.

Published in: Bioelectromagnetics 2000; 21 (8): 608-614

Aim of study (acc. to author)

To investigate the effects of magnetic field exposure (50 Hz, 2 mT) on the growth of adenocarcinoma cells, injected into mice.

Background/further details

Several different experimental protocols in terms of MF exposure timing and tumor injection were tested. A x-radiation (single 10 Gy dose) was used as positive control.



Exposure Parameters
Exposure 1: 50 Hz
Exposure duration: 6 h/day, 5 days/week, for 2 or 4 weeks

General information

exposure was performed in the following way: i) 2 weeks before tumor injection ii) 2 weeks after tumor injection iii) 2 weeks before and 2 weeks after tumor injection iv) 2 weeks with tumor injection on the 3rd day of the 2nd week v) 2 weeks before tumor injection and 10 Gy single dose x-rays
