Imaging aces aim to aid medical armamentarium
Article Abstract:
Technologies developed by intelligence, defense and aerospace industries can be used in medical imaging and other clinical applications. At a workshop about technology transfer to image-guided therapy, researchers discussed procedures that could be used in head and neck surgery, neurosurgery, and breast, prostate, and liver cancer. Potential technological problems were also discussed. Military technology is outpacing medical technology because military technology is performance-driven, and not as restricted by cost as medical technology. Physicians appear to be welcoming military technology transfer to the medical field because military technology be used to present and transmit clearer diagnostic images in real time, and may assist in developing less invasive procedures. NASA's research has medical applications in diagnostic imaging, bone calcium loss, devices to replace X-ray film, monitoring devices to measure physiological parameters such as blood gases, and specialized tissue culture chambers.

Claim that medical x-rays caused most US breast cancers found incredible
Article Abstract:
Radiation physicist John W. Gofman may have overestimated the causative role of medical x-rays in US breast cancer. Gofman quantified women's annual exposure to radiation between 1910 and 1970 and estimated their risk of breast cancer. He concluded that 62% to 75% of newly diagnosed breast cancer cases each year are caused by x-rays, which exceeds the low-risk estimates of most medical radiation authorities. Critics question why Gofman chose to publish his study in a book rather than in a peer-reviewed journal. Others argue that Gofman's risk estimate is inflated because of calculation errors. Gofman assumes that lower doses of radiation are more carcinogenic than higher doses, contrary to expert opinion. In addition, he directly translates the risk of radiation-induced cancer in Japanese atomic bomb survivors to US women, without considering lifestyle and cultural factors that effect cancer rate.

"Downwinders" Angry About Medical Screening Lack
Article Abstract:
Residents of Washington State are angry about the delay in funding a program mandated by the Superfund law to screen residents exposed to radiation from the Hanford nuclear weapons facility. The so-called Downwinders' have filed a lawsuit demanding that the Department of Energy provide the funds requested by the US Public Health Service's Agency for Toxic Substances and Disease Registry (ATSDR) to set up the Hanford Medical Monitoring Program. An estimated 14,000 Hanford residents received at least 10 rads of radiation to their thyroids when they were children, which increases their risk of thyroid cancer.
