Aim of study (acc. to author)

To investigate the effects of 2450 MHZ CW microwave exposure on human blood platelets in vitro.

Background/further details

Before exposure the obtained platelets were labeled by incubation with 14C-serotonine to examine the platelets release reaction.

Main outcome of study (acc. to author)

The results on platelet lysis and membrane permeability revealed no significant changes. Whereas the results on serotonin release indicate an stimulating effect of irradiation on the platelet release reaction, but these findings were considered to be only thermal effects.
