I have a question which I hope you can answer or possibly provide a direction to get an answer. As you may remember, I teach a research class. One of my students, a junior, has been studying the effect of non-ionizing radiation on the growth of penicillium ilalicum for two years. Last year his measurment techniques were somewhat crude. This year he has obtained a Gauss meter and digital camera. The source of the radiation was 9 fish tank pumps.

I am puzzled by your findings. I checked PubMed (the public on-line library of NLM/NIH, at for similar findings. I found a paper describing that yeast (Saccharomyces cerevisiae) was not affected by 900 MHz radiation as produced by mobile phones

(Bioelectromagnetics 2000 Oct;21(7):515-23). In anohter paper the effect of 50 Hz radiation on Propionibacterium was assessed (Bioelectromagnetics 2000 May;21(4):302-11).

You can check at whether this journal contains other papers relevant to your observation?
