1 Note that the 5,000 mrem dose guideline represents the standard occupational dose limit for one year.
2 The 50,000 mrem dose guideline is a level at which minor effects from short-term radiation exposure are possible. Note that this guideline applies to a once-in-a-lifetime event.
3 Specific approval and controls are required to exceed this turn-back exposure rate.
