HHS-OASH-2026-0397-2888 https://www.regulations.gov/comment/HHS-OASH-2026-0397-2888 I studied biology to degree level, graduating in 1994. The subject of cell science was a favourite of mine. My comment arises from the fact that there is evidence that the current, Safe E/M Radiation Level is much too high, current levels causing changes in biological cellular activity. 5G masts are of concern in the UK, and LED street lighting is a further issue. While you can put up heavy curtains to dim the light, the radiation is of course unimpeded. Furthermore, one environmental consequence of LED lighting is that insect reproduction near these lights is mostly absent. A great deal more research into the neurological and neurophysiological response to these EMF sources should be carried out if we are to set a more realistic Safe level of exposure for the general public and all those who work near EMF sources.
