Dose Received by Technologists Using Different Methods to Shield Injection Dose
| Shielding type | n | Mean dose ± SD | ||
|---|---|---|---|---|
| μSv/procedure | nSv/MBq | |||
| None | 9 | 3.4 ± 1.7 | 9.7 ± 2.3 | |
| Primary | 9 | 3.6 ± 1.5 | 8.6 ± 2.9 | |
| Primary and secondary | 69 | 1.9 ± 0.9 | 4.5 ± 2.2 | |
Dose includes period of dose transport and injection. Primary and secondary shielding refers to total of 32.7 mm of lead-equivalent shielding.
