Appendix 2 FDA Notice DEPARTMENT OF HEALTH AND HUMAN SERVICES Public Health Service Food and Drug Administration Rockville MD 20857 Update on Possible Hazards of Traffic Radar Devices July 20 1992 TO CITY COUNTY STATE AT FEDERAL POLICE OFFICIALS Recent stories in the news media have focused attention on the possibility that the traffic radar devices used by police officers might increase their risk of cancer particularly testicular cancer The Food and Drug Administration FDA has prepared the following information to inform police officers about what is known and what remains unknown about this guestion We urge you to make this Update available to the officers under your jurisdiction Feel free to photocopy this Update as needed What kind of radiation is emitted by traffic radar units These devices emit microwave radiation similar to the type produced inside microwave ovens but at a power level more than 10 000 times lower The radiation travels from the front of the radar device in a narrow cone shaped beam although some of it may be reflected back from hard surfaces such as metal and glass The amount of radiation decreases rapidly with distance from the source so that the farther the devices are kept from the body the lower the exposure Is there any experimental evidence that the levels of microwave radiation from a traffic radar device can be dangerous Although it is known that very high levels of micr
