Radiological investigations are very important in diagnosis of many ailments in spite of their known hazards. The knowledge of radiation doses received by the patients during radiological procedure is necessary and all efforts must be made to keep the radiation dose to its minimum level. In the present study, the author has measured the radiation doses received by the patients during various radiological procedures. 193 x-ray installations in udaipur division were visited and the patient radiation dosimetry was carried out using caSO4 : Dy thermoluminescence (TL) discs. It is observed that chest radiography is the commonest radiological procedure and accounts for 37% of all radiological investigations; 70% of the chest x-rays were normal without any pathology. The frequency of radiological procedures for Udaipur division was estimated and observed that, on an average, 537 radiological procedures are carried out per year for population of 100000, The contribution of per capita radiation dose due to radiological procedures over and above the natural background radiation dose works out to be 22 pGy / year. The detailed results are discussed in the present communication.
