Health effects from exposure to low dose radiation are always difficult to assess. It has long been assumed that there is no “smoking gun” to link a particular health issue to causation when dealing with the random effects of radiation exposure (especially when there are many other environmental and genetic factors to consider). Looking at a single type of health effect that can occur from radiation exposure, Thyroid Cancer (TC), researchers at Penn State University have postulated that Radiation-induced Thyroid … Continue Reading →
I get questions periodically from pilots and flight attendants about occupational radiation exposure. It has been known for some time that the exposures received by some flight personnel would require monitoring with dosimeters if they were working in the medical or nuclear industries.
The challenges to determining dose to a person in flight is complex in different ways than dosimetry on the surface of the planet. High altitude radiation includes particles and rays from distant star … Continue Reading →
Dr.Ken Buessler, senior scientist at Woods Hole Oceanographic Institution and Director of the Center for Marine and Environmental Radioactivity, has launched a crowd funded project to assess ocean contamination from the Fukushima Daiichi event. See information on this program here.
Safecast has compiled reports and assessments of impacts on the Pacific Ocean, and added some perspective here.
We are continuing to cover the Surferʻs Beach, Half Moon Bay analysis of radioactive sand. We have determined it is not related to … Continue Reading →
