RADIATION SURVEILLANCE PROGRAMME AND CONTROL OF PERSONNEL EXPOSURE DURING 2001-2007 AT RPHD, RLG

摘要

Radioisotopes find innumerable applications in medical, industrial and agricultural applications. Radiopharmaceutical division is engaged in activities to promote peaceful uses of radioisotopes and radiation. In Radiopharmaceutical division production and processing of radio chemicals take place for low activity sealed sources for various applications such as brachytherapy, references sources for calibration, sources for industrial application. These sources are then supplied to end users through BRIT. Radiopharmaceutical division handles significant amount of beta and gamma emitting radioisotopes in solid and in solution form. Board of Isotopes and Radiation Technology (BRIT) has committed supply of these sealed sources to various hospitals and industrial institutions in India. Annually, TBq level of radioisotopes are handled in facilities such as - fume hood, shielded production plant, glove boxes, RLG, BARC. This paper brings out a detailed account on the radiological surveillance provided during the production of these radio chemicals and sources implementing As Low As Reasonably Achievable (ALARA). The decrease in collective dose per activity handled is the outcome of improved operation practices, radiation surveillance and safety compliance carried out at various stages of production.
