During the past three years the National Bureau of Standards and the Bureau of Radiological Health have been conducting a survey of /sup 60/Co teletherapy facilities to determine their accuracy in exposing a phantom to a prescribed dose. As of May 1977, some 700 units were surveyed of the approximately 1000 which are licensed to administer therapy in the United States. Preliminary data indicate that about two-thirds of the respondents were able to calculate the specified 300 rad dose within 5 rad, while 8% reported values which varied from the specified dose by more than 15 rad. The mean exposure determined for a set of dosimeters differed from the 300 rad value by less than 5% for 83% of units; 4% of the units produced an exposure which differed by more than 10% of the target value.
