Table 3-3. Degree-of-Risk Criteria

Negligible risk:

≦

50

Moderate risk:

≦

70

RES-0 units

No exposure

Emergency risk:

≦

150

Negligible risk:

≦

10

Greater than 0 but less

Moderate risk:

≦

30

RES-1 units

than or equal to 70

Emergency risk:

≦

110

Any further exposure is considered to exceed a negligible

Greater than 70 but less

RES-2 units

or moderate risk. Emergency risk: ≦ 40

than or equal to 150

RES-3 units

Greater than 150

All further exposure will exceed the emergency risk.

1

Categories are based on previous exposure to radiation.

2

Reclassification of units from one RES to a less serious one is made by the commander upon advice of

the surgeon after observing the actual state of the health of the exposed personnel.

3

All exposures to radiation are considered total body and simply additive. No allowance is made for

body recovery from radiation injury.

4

Risk levels are graduated within each exposure state to provide more stringent criteria as the total

radiation dose accumulated becomes more serious. The exposure criteria given for RES-1 and RES-2

units should be used ONLY when the numerical value of a unit's total past cumulative dose is

UNKNOWN. Otherwise, the criteria for the desired degree of risk should be obtained by SUBTRACTING

the numerical value of the unit's dose from the RES-0 CRITERA for the desired degree of risk.

5

Each of the degrees of risk can be applied to radiation hazards resulting from enemy or friendly

weapons, or both, and from initial nuclear radiation resulting from planned friendly supporting fires.
