Health Physics, first published in 1958, has provided a wide variety of radiation safety professionals including health physicists, nuclear chemists, and physicians with interest in nuclear and radiological medicine to stay on the cutting edge of scientific and technological advances in the field of radiation safety for these and other disciplines in science and engineering. With the many advances in medicine, industry and research using radioactive materials and radiation machines, there is an ongoing need for cutting edge information on radiation safety. The Journal along with its quarterly supplement, Operational Radiation Safety, provides features that allow readers to understand more about the topics that interest them. These features include original papers, technical notes, articles on advances in practical applications, editorials, and correspondence that report on the latest findings in theoretical practical and applied disciplines, of epidemiology and radiation effects; radiation biology and radiation medicine; fate and transport of radioactive materials in biological systems to name just a few. Scientists, physicians and engineers alike will find useful information regarding radiation safety.
