38th Lauriston S. Taylor lecture: on the shoulders of giants - radiation protection over 50 years.

Linear, no threshold model in radiation protection and safety: standards thrive on ‘assumptions’ and not on science-based evidence

Judgement in Achieving Protection Against Radiation by Lauriston S. Taylor IONIZING RADIATION AS A TOXIC AGENT

Ionizing radiation has been known to man for nearly eighty-five years and for only a few weeks less than that time it has been recognized that if people are exposed to enough ionizing radiation they may suffer injury of an obvious and definable nature. What is not known is whether there is some lower limit to the exposure below which man will not suffer injury and above which he will. There is ...

Does Exposure to Static Magnetic Fields Generated by Magnetic Resonance Imaging Scanners Raise Safety Problems for Personnel?

MRI workers are occupationally exposed to static and time-varying gradient magnetic fields.  While the 24-hour time-averaged exposure to static magnetic fields is about a few mT, the maximum static field strength can be as high as 500 mT during patient setup. Over the past several years, our laboratory has performed extensive experiments on the health effects of exposure of animal models and h...
