might at equilibrium lead to an increased incidence of leukemia, at
most, of about ten cases per year per million persons exposed.
The genetic dose to the population should be kept to the minimum
amount consistent with necessity and should certainly not exceed 5 rems

No single type of population exposure should take up a
O+SProportzonate share of the total of the recommended dose limit.
