ES&H Manual Radiation Control Supplement

Appendix 2A

Guidelines for Control

of Emergency Exposures

In extremely rare cases, emergency exposure to radiation may be necessary to rescue personnel or to protect major property. The recommended dose limits for personnel performing these operations are listed below.

Dose Limit (Whole Body)	Activity Performed	Conditions
5 rem	All
10 rem	Protecting major property	Where lower dose limit not practicable
25 rem	Lifesaving or protection of large populations	Where lower dose limit not practicable
>25 rem	Lifesaving or protection of large populations	Only on a voluntary basis to personnel fully aware of the risks involved
Notes: 1. Values are from EPA Manual of Protective Action Guides and Protective Actions for Nuclear Incidents, EPA 400-R-92-001. Values are guidelines only; emergency operations would be conducted with due consideration given to maintaining doses as low as feasible under the circumstances. 2. The dose limit to the lens of the eye is three times the listed values. 3. The dose limit to the skin of the whole body and the extremities is ten times the listed values. 4. Doses received in authorized emergency response activities are accounted for separately from the doses received under the limits in 10 CFR 835.202.
