Abstract
Abstract The doses delivered to some critical organs of patients and staff during cerebral angiography, X-ray computer assisted tomographic scanning and 99Tcm brain scanning have been measured or assessed. The results show that doses received by staff and by the patients' gonads are generally quite low. However, patients having two or more of the investigations could receive skin and orbit doses in excess of 25 rad.

Recent interest in radiation dose to the cornea during neuroradiological investigations (Isherwood et al., 1975) prompted us to test our own figures during cerebral angiography. Thermoluminescent dosemeters (TLD) appropriately marked right and left were placed over the eyes of patients undergoing cerebral angiography. Our equipment consists of 24 × 30 cm Puck film-changers with Siemens Special Super High Speed screens and a Siemens Tridoros 5S generator.

Cerebral angiography provides valuable information for use in the clinical management of patients but can result in relatively high radiation doses to patients and staff due to the extended fluoroscopy time and number of images acquired during an examination. In this study, extremity doses to radiologists and scrub nurses working in a neuroradiological centre were monitored during a 3 month period using thermoluminescent dosemeters (TLDs). Electronic personal dosemeters were also used to monitor...
