On February 23, the National Toxicology Program released its request for proposals (No. NIH-ES-04-06) for large-scale animal studies to evaluate the possible toxic and carcinogenic effects of cell phone radiation. The FDA originally asked for these studies more than five years ago (see MWN, N/D99, p.5; J/A00, p.5; M/J01, p.1; and M/J03, p.17). The total cost of the project will be on the order of $10 million. Proposals are due by April 8.
