The 1993 Report of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) has provided extensive data on medical radiation exposures worldwide and exposures therefrom. The present paper summarises the data from UNSCEAR 1993 as relevant to diagnostic radiology and radiotherapy. Data for India are separately indicated. Countries have been categorised into four levels of health care, based on the population per physician, (India is in level 11). Data have been grouped into three time periods, 1975-79, 1980-84 and 1985-88. Data are provided for the frequencies of different types of diagnostic examinations, average patient doses therefrom, annual collective effective doses (in man-Sv), and per caput effective doses. Similar data are discussed for radiotherapy (both teletherapy and brachytherapy). Temporal and regional trends and variations in dose for given procedures for each level of health care, as well as for the world as a whole are discussed. Occupational exposures in diagnostic radiology and radiotherapy are finally discussed.
