Abstract: 99Mo/99mTc generators are widely used in nuclear medicine to produce technetium-99m for diagnostic imaging. Ensuring safe handling and transport of these generators is essential for protecting workers, the public, and the environment. This study aimed to measure radiation levels for Monorol 99Mo/99mTc generator packages upon receipt at a nuclear medicine department to verify compliance with international safety standards (IAEA, 2018).
Forty-four generator packages were assessed during 2016–2018. Dose rate measurements were taken using a calibrated survey meter (RADOS RDS-200, calibration factor 0.94) at four positions: direct top surface, one meter above top surface, direct outer surface, and one meter from outer surface. Results were analyzed separately for 30 GBq and 15 GBq generators, and compared with reference studies (Ahasan, 2004) and regulatory thresholds (IAEA, 1999).
All measured values were below IAEA transport limits of 2mSv/hr at package surface and 0.1mSv/hr at one meter (IAEA, 2018).
This study concluded that all generator packages met IAEA and ALARA safety requirements, demonstrating effective shielding and transport practices.
