To investigate the effects of an electromagnetic field emitted by a mobile phone on iron parameters in the serum of rats.
Male rats were divided into 4 groups (n=8 per group): 1) cage control, 2) sham exposure group, 3) exposure group with mobile phone in speech mode and 4) exposure group with mobile phone in stand mode.
| Exposure | Parameters |
|---|---|
|
Exposure 1:
890–915 MHz
Modulation type:
AM
Exposure duration:
2 hours/day for 10 weeks (unclear if mobile phone was "standby" or "off" for the other 10 hours when rats remained in the plastic boxes)

Exposure 2:
890–915 MHz
Modulation type:
AM
Exposure duration:
12 hours/day for 10 weeks
standby modus

| Chamber | circular plastic boxes were used for exposure and sham exposure; rats were kept in these boxes for 12 hours |
| Setup | 4 rats were exposed simultaneously; the mobile phone was placed 1 cm below and in the middle of the boxes; rats were placed in the box with their testes directed towards the mobile phone |
| Sham exposure | A sham exposure was conducted. |
| Frequency | 890–915 MHz |

No significant differences between the exposed groups (groups 3 and 4) and the cage control (group 1) were found regarding the level of iron and ferritin. However, the unsaturated and the total iron-binding capacity were significantly decreased in the sham exposure and exposure groups (groups 2, 3, and 4) compared to the cage control (group 1) (Remark EMF-Portal: Results taken from the table, significant difference between sham exposure and control group was not mentioned in running text).
The authors conclude that exposure of rats to an electromagnetic field emitted by a mobile phone could influence the unsaturated and the total iron-binding capacity.
