Last night the National Toxicology Program (NTP) of the National Institutes of Health issued the first in a series of reports that contains partial findings from their long-awaited, $25 million study of the cancer risk from cell phone radiation. This report summarizes the study of long-term exposure to cell phone radiation on rats. The report on mice will be issued at a later date.
According to the report:
“Given the widespread global usage of mobile communications among users of all ages, even a very small increase in the incidence of disease resulting from exposure to RFR [radiofrequency radiation] could have broad implications for public health.”Overall, thirty of 540 (5.5%), or one in 18 male rats exposed to cell phone radiation developed cancer. In addition,16 pre-cancerous hyperplasias were diagnosed. Thus, 46 of 540, or one in 12 male rats exposed to cell phone radiation developed cancer or a pre-cancerous lesion as compared to none of the 90 unexposed male rats. The two types of cancer examined in the exposed rats were glioma and schwannoma. Both types have been found in human studies of cell phone use.
In the group exposed to the lowest intensity of cell phone radiation (1.5 watts/kilogram or W/kg), 12 of 180, or one in 15 male rats developed cancer or a pre-cancerous lesion.
This latter finding has policy implications for the FCC’s current cell phone regulations which allow cell phones to emit up to 1.6 W/kg at the head or near the body (partial body Specific Absorption Rate or SAR).
The NTP study is likely a “game-changer” as it proves that non-ionizing, radiofrequency radiation can cause cancer without heating tissue.
The results of the study reinforce the need for more stringent regulation of radiofrequency radiation and better disclosure of the health risks associated with wireless technologies — two demands made by the International EMF Scientist Appeal — a petition signed by 220 scientists who have published research on the effects of electromagnetic radiation.
Along with other recently published studies on the biologic and health effects of cell phone radiation, the International Agency for Research on Cancer of the World Health Organization should now have sufficient data to reclassify radiofrequency radiation from “possibly carcingogenic” to “probably carcinogenic in humans.”
