WASHINGTON--According to a report issued by the General Accounting
Office (GAO), federal agencies have insufficient scientific knowledge
to take regulatory action on the use of portable cellular telephones.
There has been no completed research on long-term human exposure
to the low levels of radiation generated by these phones, and
research findings on exposure to other sources of low-level radiofrequency
radiation are inconclusive, the report said.
The GAO has called for the FDA and the National Science Foundation
to determine the links, if any, between cellular telephone use
and human disease.
