B. A Method of Estimating Doses From Activity in a Water Supply
The value of 5 x i073 microcuries per milliliter at D+ 3 days
after a detonation has been set as an operational guide for activity
concentration in water.
This may be evaluated in several ways, one
of the most extreme being that water containing this amount of activity
is stored and used as the sole supply for a lifetime at the rate of
2200 milliliters per day
