  • The National Council on Radiation Protection and Measurements (NCRP) published Report No. 48, Radiation Protection for Medical and Allied Health Personnel in 1976. Many changes in medical practice and procedures involving ionizing radiation have occurred in the intervening 13 years. As a result, the Council determined to prepare this new report to supersede NCRP Report No. 48. The primary objective of this new report is to update the material to include new radiation sources used in medicine.

  • Second, we assess whether the differences in the car-employment effect between black and white workers increases with the severity of spatial mismatch. If spatial mismatch yields a car- employment effect for black workers that is larger than that for white workers, then the black-white difference in the car-employment effect should be larger in metropolitan areas where blacks (relative to whites) are particularly isolated from employment opportunities. We test this proposition using data from several sources. ...

  • Personal protective equipment (PPE) includes clothing or other special equip- ment that is issued to individual workers to provide protection against actual or potential exposure to ionizing radiations. It is used to protect each worker against the prevailing risk of external or internal exposure in circumstances in which it is not reasonably practicable to provide complete protection by means of engineering controls or administrative methods. Adequate personal protection depends on PPE being correctly selected, fitted and maintained.

  • Radiation Marrow aplasia is a major acute sequela of radiation. Radiation damages DNA; tissues dependent on active mitosis are particularly susceptible. Nuclear accidents can involve not only power plant workers but also employees of hospitals, laboratories, and industry (food sterilization, metal radiography, etc.), as well as innocents exposed to stolen, misplaced, or misused sources.

  • The European Union’s CAREX database of occupational exposures to carcinogens estimated that in the early 1990s 22-24 million workers in the then 15 EU member states were exposed to carcinogens classified as group 1 by the International Agency for Research on Cancer – those known to cause cancer in humans. Overall, 32 million workers, 23 per cent of the working population, had workplace exposures associated by the CAREX database with an occupational cancer risk.

  • A variety of occupational risks is known to cause cancer. Every year more than seven million people die of cancer. Forty percent of these cases could be prevented which means that one in every ten cancer deaths is preventable through interventions targeted on exposure in the working environment. The articles in this issue of GOHNET highlight some aspects of the problem and the prevention of occupational cancer.

  • The NRC has adopted a risk-informed, performance- based approach to regulation. The result is that the procedural aspects of a licensee’s radiation protection program are not required to constitute “best practice” in the medical use of radionuclides, as long as perfor- mance outcomes are in compliance. The continued need for some of the suggested procedures in this book should be considered in light of the licensee’s own prior experience obtained during reviews of its radiation protection program.
