Crack the 2026 HESI Radiologic Tech Exam – Radiate Success and Shine Bright!

The concept here is that different parts of the body have different occupational dose limits. Extremities like the hands can tolerate higher localized exposure than the whole body, so they have their own separate limit.

For hands, the annual permissible equivalent dose is 500 mSv. This reflects the need to limit long-term skin and tissue risks from repeated work with radiation, while recognizing that the hands may receive higher localized doses during procedures. By comparison, the whole-body effective dose limit is much lower (about 20 mSv per year on average over five years), illustrating the difference between organ-specific limits and whole-body protection.

Other numbers don’t match the established extremity limit: they’re either too low for hands or not the standard occupational limit for this body area.
