Kategoria BISAC: Science >> Radiation

A much-needed working resource for health physicists and other radiation protection professionals, this volume presents clear, thorough, up-to-date explanations of the basic physics necessary to address real-world problems in radiation protection. Designed for readers with limited as well as basic science backgrounds, Physics for Radiation Protection emphasizes applied concepts and carefully illustrates all topics through examples as well as practice problems.

This thesis offers an accessible guide to biomedical phase-contrast imaging with over 20 radiographic illustrations. It focuses on research to improve radiography, and particularly mammography applications, by using a novel X-ray imaging modality that exploits the wave-nature of X-rays, rather than just their absorption in tissue. Further, it explores a broad range of potential applications from the assessment of breast cancer and the evaluation of microcalcification clusters, to the examination of renal stones.

X-ray imaging is an indispensable tool in modern medical...

RADIOACTIVE CLOUDS OF DEATH OVER UTAH

From 1950 to the 1958 moratorium on atmospheric testing, the Atomic Energy Commission detonated over 100 atomic bombs at the Nevada Test Site. The inhabitants of St. George, Utah--the so-called downwinders--were repeatedly in the fly zone of these toxic, windblown clouds--so much so that St. George became known nationwide as Fallout City, USA.

In the fall of 1979, Stewart Udall, along with a team of lawyers, came to St. George to announce plans for a class-action lawsuit against the United States because the local people were struggling with...

Since the discovery of X-rays and radioactivity, ionizing radiations have been widely applied in medicine both for diagnostic and therapeutic purposes. The risks associated with radiation exposure and handling led to the parallel development of the field of radiation protection.
Pioneering experiments done by Sanche and co-workers in 2000 showed that low-energy secondary electrons, which are abundantly generated along radiation tracks, are primarily responsible for radiation damage through successive interactions with the molecular constituents of the medium. Apart from ionizing...
