Proposal to reduce the carcinogenic character of electromagnetic radiation (EMR)

Non-ionizing electromagnetic radiation (NIEMR) interacts with matter in 3 ways:\footnote{M. Lundquist, {\bf BAPS 51}(1):518 (2006).} it can transfer energy, linear momentum, and angular momentum to matter. At high frequencies ({\it e.g.}, microwaves), evidence exists of a carcinogenic effect on living creatures irradiated with NIEMR.\footnote{M. Lundquist, {\bf BAPS 49}(1):1296 (2004).} Which effect is carcinogenic? NIEMR heats matter by transfer of energy; this effect is used to {\bf kill} established cancers. Transfer of linear momentum to matter merely alters the local pressure; cancer has never been associated with pressure changes. So the transfer of non-zero angular momentum to matter is the interaction most likely to be carcinogenic. EMR polarization can be circular, elliptical, or plane. Only plane-polarized EMR possesses {\bf zero} angular momentum and therefore {\bf cannot} transfer any angular momentum to matter. Everything that is true of NIEMR is also true of ionizing EMR, so it seems likely that the carcinogenic potential of {\bf all} EMR (whether ionizing or non-ionizing) will be minimized by filtering it or taking other steps to make it plane-polarized before using it to irradiate a person or animal. Obvious applications are medical/dental X-rays and the full body scanners used on travelers at airports.
