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.
This Report emphasizes management’s responsibility in training
employees, and presents criteria for identifying training
requirements for different groups of employees. The type of personnel
to be trained is treated and an extensive coverage of the design
and development of radiation safety programs is provided. The
learning environment and training aids are discussed and guidance
on the audit of training programs is given.
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.
Objectives: To assess the situation of radiation safety, health and illnesss of health workers exposed to ionizing radiation in Thai Nguyen in the year 2012; To analyze the association between radiation safety and health of health workers at health facilities using ionizing radiation in Thai Nguyen; To evaluate the efficacy of some interventions about ensuring radiation safety and health of health workers at health facilities using ionizing radiation in Thai Nguyen.
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
