1. The Bureau of Medicine and Surgery has no objection to the increase
in radiation dose for personnel in Project 3.4, Operation HARDTACK, from
3r/13-week period to 4r/13-week period.
This proposed increase is in
accordance with a revision of National Bureau of Standards Handbook 59,
entitled "Permissible Dose for External Sources of Ionizing Radiation."
However, it must be emphasized that the Bureau of Medicine and Surgery
desires that personnel exposure be kept as low as possible, even at che
expense of an early entry into the target area.
2.
It is requested that the Commander, Norfolk Naval Shipyard, direct
this request to the Commander, TF-7, as & policy matter coming under
that Commander's cognizance.
