“…Zanzonico's approach did not consider the heterogeneous biodistribution of radiopharmaceuticals. Using Monte Carlo simulations, Soares et al [23] have calculated radiopharmaceutical-specific dose rate constants and absorption fractions with a voxelised human phantom and the biokinetic data from ICRP 128 [24], which may seem ideal to consider. The absorption fractions using the two approaches are presented and compared in table 1.…”

This article reviews the essential considerations in planning and designing nuclear medicine departments. There are four proposed categories to consider as ‘shielding commissioning factors’ (SCF). The first SCF: ‘Patient flow optimisation and workload’ emphasises the importance of carefully considering patient flow in the departmental design, which would impact the cost of the shielding and the management of radioactive patients. The second SCF: ‘Equipment and space allocation’ discusses the principles of space allocations in the department for cost-effective designs. The third SCF: ‘Shielding calculation methods’ reviews the methodologies of shielding calculations in nuclear medicine to offer a standardised approach. The fourth SCF: ‘Shielding integrity’ reviews the plan to inspect, eyewitness and verify shielding integrity. All discussions were supplemented by practical examples. Overall, this article aims to be a practical manual which health or medical physicists can use when providing counsels to the design committee.

The self-attenuation of a patient’s body is an important factor in nuclear medicine for designing radiation shielding. Taiwanese reference man (TRM) and Taiwanese reference woman (TRW) were constructed to simulate the body dose rate constant and the effective body absorption factor for 18F-FDG, 131I-NaI and 99mTc-MIBI using the Monte Carlo technique. For TRM, the maximum body dose rate constants for 18F-FDG, 131I-NaI and 99mTc-MIBI were 1.26 × 10−1, 4.89 × 10−2 and 1.76 × 10−2 mSv-m2/GBq-h, respectively, at heights of 110, 110 and 100 cm. For TRW, the results were 1.23 × 10−1, 4.75 × 10−2 and 1.68 × 10−2 mSv-m2/GBq-h at heights of 100, 100 and 90 cm. The effective body absorption factors were 32.6, 36.7 and 46.2% for TRM and 34.2, 38.5 and 48.6% for TRW. Regional reference phantoms along with the derived body dose rate constant and effective body absorption factor should be used for determining regulatory secondary standards in nuclear medicine.
