IAEA model project on upgrading the radiation protection infrastructure: background--origin--implementation. International Atomic Energy Agency Model.

The International Atomic Energy Agency Model Project is a focused management program to improve the Radiation Control Programs primarily in developing countries. The effort was initiated in 1994 as a result of RAPAT mission reports and incidents around the world involving injuries and some deaths from uncontrolled and misuse of radioactive sources. This indicated that many countries were not implementing the IAEA Basic Safety Standards. The initial phase covered 52 countries and resulted in 69% passing legislation and 75% had some type of regulatory authority and 40% had regulations and licensing and inspection capabilities. But, the overall averages masked disappointment for some countries in West Asia where only 22% had regulations and 33% had a licensing and inspection program. In Africa 24% had regulations and 29% had a licensing and inspection program. Plans were approved to extend the effort to an additional 30 countries over the next 4 y.

The international atom: evolution of radiation control programs.

Under the Atoms for Peace program, Turkey received a one MWt swimming pool reactor in 1962 that initiated a health physics program for the reactor and a Radiation Control Program (RCP) for the country's use of ionizing radiation. Today, over 13,000 radiation workers, concentrated in the medical field, provide improved medical care with 6,200 x-ray units, including 494 CAT scanners, 222 radioimmunoassay (RIA) labs and 42 radiotherapy centers. Industry has a large stake in the safe use of ionizing radiation with over 1,200 x-ray and gamma radiography and fluoroscopic units, 2,500 gauges in automated process control and five irradiators. A 48-person RCP staff oversees this expanded radiation use. One incident involving a spent 3.3 TBq (88 Ci) 60Co source resulted in 10 overexposures but no fatalities. Taiwan received a 1.6 MWt swimming pool reactor in 1961 and rapidly applied nuclear technology to the medical and industrial fields. Today, there are approximately 24,000 licensed radiation workers in nuclear power field, industry, medicine and academia. Four BWRs and two PWRs supply about 25% of the island's electrical power needs. One traumatic event galvanized the RCP when an undetermined amount of 60Co was accidentally incorporated into reinforcing bars, which in turn were incorporated into residential and commercial buildings. Public exposures were estimated to range up to 15 mSv (1.3 rem) per annum. There were no reported ill effects, except possibly psychological, to date. The RCP now has instituted stringent control measures to ensure radiation-free dwellings and work places. Albania's RCP is described as it evolved since 1972. Regulations were promulgated which followed the IAEA Basic Safety Standards of that era. With 525 licenses and 600 radiation workers, the problem was not in the regulations per se but in their enforcement. The IAEA helped to upgrade the RCP as the economy evolved from one that was centrally planned economy to a free market economy. As this transition takes place, public radiation exposures in the medical field will continue to be high until the old x-ray equipment is phased out. A small conscientious health physics staff works with limited resources to keep radiation exposures at acceptable levels. These three country RCPs, as they have evolved, have some commonality. Today, all radiation installations are licensed, both for radioactive material and x-ray equipment. Radiation workers are individually licensed or registered. All RCPs have, or are striving to have, their radiation regulations conform to ICRP 60 recommendations as spelled out in the Basic Safety Standard (1996). Finally, all three countries have as yet to find a permanent solution for their radioactive waste.

Historical perspective: a forward look, a backward look.

This paper summarizes how the problems of fallout, genetics, radioactive waste, and regulatory control of radiation were perceived by Dunning, Straub, Taylor, and others in 1955 at the inaugural meeting of the Health Physics Society. It was stated that health physicists had a great opportunity to resolve these problems and to avoid past mistakes. Throughout the 1950s, health physicists made major contributions to elucidating the fallout problem and contributed to its resolution, and it can be considered a success story. Waste disposal is not considered to be a success to date. A major difference has been the lack of political will to grapple with a perceived "no win" situation. The evolution of radiation limits is briefly traced over the past 37 y from voluntary standards to rigorously enforced regulations demanded by society. This paper speculates that the changing international scene makes the United States the pre-eminent nuclear power which will challenge future health physicists to maintain a balance between the control of radioactive material and its peaceful applications.
