Screening truffles for radioactivity 30 years from Chernobyl
Some forest mushrooms, such as wild porcini, can accumulate dangerous levels of radioactivity from the soils they grow in. But until now it was unclear if the same was true for truffles, fungi that range among the most expensive foods in the world. Researchers have analyzed Burgundy truffles collected in central Europe and found they contain only negligible amounts of radioactive cesium, being safe for consumption. The results are published Feb. 25 in Biogeosciences. (2016-02-25)

Radiation for health
For decades, we have been told that exposure to radiation is dangerous. In high doses it is certainly lethal and chronic exposure is linked to the development of cancer. But, what if a short-term controlled exposure to a low dose of radiation were good for our health. Writing in today's issue of the Inderscience publication the International Journal of Low Radiation, Don Luckey, makes the startling claim that low dose radiation could be just what the doctor ordered.
