Bioeffects induced by exposure to microwaves are mitigated by superposition of ELF noise.

Aim of study (according to author)
The authors speculated that the superimposition of electromagnetic noise fields, which have been shown to inhibit biological responses due to extremely low frequency exposure (see publication id 344 and publication id 2809), may also inhibit the effects of modulated microwaves.
The aim of the study was to investigate this possibility by conducting experiments in which biological samples were exposed concurrently to amplitude
modulation and extremely low frequency noise fields.
Background/further details:
L929 cells were exposed to 60 Hz amplitude modulated microwave fields or a 50 Hz burst-modulated DAMPS (Digital Advanced Mobile Phone System) digital cellular phone field at levels known to produce ornithine decarboxylase enhancement, together with band-limited 30-100 Hz extremely low frequency noise
with root mean square amplitude of up to 10 µT.

Main outcome of study (according to author)

In both cases, the ornithine decarboxylase activity enhancement was found to decrease exponentially as a function of the noise root mean square amplitude: With 60 Hz amplitude modulated microwaves, complete inhibition (of ornithine decarboxylase enhancement effect) was obtained with noise levels at or above
2 µT. With the DAMPS digital cellular phone signal, complete inhibition occurred with noise levels at or above 5 µT.
These findings suggest a possible practical means to inhibit biological effects from exposure to both extremely low frequency and microwave fields.
