ICNIRP Note on Recent Animal Carcinogenesis Studies

 

In relation to the revision of the ICNIRP RF Guidelines, ICNIRP is publishing a note on recent animal carcinogenesis studies.

Following is the excerpt:

"Two recent animal studies investigating the carcinogenic potential of long-term exposure to radiofrequency electromagnetic fields (EMFs) associated with mobile phones have been released: one by the U.S. National Toxicology Program (NTP 2018a, b) and the other from the Ramazzini Institute (Falcioni et al. 2018). These studies, among others, have been taken into account during revision of the ICNIRP radiofrequency exposure guidelines. However, both studies have inconsistencies and limitations that affect the usefulness of their results for setting exposure guidelines, and both need to be considered within the context of other animal and human carcinogenicity research. Overall, based on the considerations outlined below, ICNIRP concludes that these studies do not provide a reliable basis for revising the existing radiofrequency exposure guidelines.

Conclusion:

Although the NTP (2018a, b) and Falcioni et al. (2018) studies used large numbers of animals, best laboratory practice, and exposed animals for the whole of their lives, consideration of their findings does not provide evidence that radiofrequency EMF is carcinogenic. NTP reported that their strongest findings were of increased malignant cardiac schwannoma in male rats, however that is not consistent with the results of Falcioni et al. (2018), is not consistent with the NTP female rat nor male or female mouse results, and is not consistent with the radiofrequency EMF cancer literature more generally. While results from epidemiological studies suggest vestibular schwannoma is an outcome of interest, this is not true for malignant cardiac schwannoma. NTP found no increase in schwannoma overall or for vestibular schwannoma. Further, as multiple comparisons were not controlled for in the NTP study, there is no indication that the increased incidence of malignant cardiac schwannomas in male rats was more than what would be expected by chance alone. ICNIRP considers that the NTP (2018a, b) and Falcioni et al. (2018) studies do not provide a consistent, reliable and generalizable body of evidence that can be used as a basis for revising current human exposure guidelines. Further research is required that addresses the above limitations."
