S>A long-term investigation was conducted at Eniwetok Atoll during
1954-57 to determine the rate of recovery of land plants damaged by the
radiation, shock, and heat blast of the Nectar detonation in 1954. At Belle
Island seven plant species were tagged, measured, and photographed before
the detonation. At approximately monthly intervals after the detonation for
a period of ten months, and again after an interval of six months, the
plants were observed and photographed. The first indication of recovery was
observed on the eighth day, at which time buds were noticeable on stems of
Scaevola and Messerschmidia plants. In a month’s time, most of the plants
had formed new leaves and some had produced flowers and fruits. In six
months, the general condition of the vegetation was similar to that which
existed before the detonation. Two plants, Guettarda and Portulaca, which
were unhealthy at ten months, had improved by the sixteenth month.
Photographs of the recovery of some of the plants are included, as well as
a discussion of agents other than radiation which have been reported to
cause similar damage to plants of the coral atolls of the Pacifie Ocean.

Structures are subjected to a 50-kt blast, in order to obtain fundamental
data on structures subjected to blast loading, to observe the response of
the structures under this loading, and to determine the relative
blast-resistance merits of several structural types. Modes of faiMure are
determined. Shaped structures are found to be superdor to rectangular
structures. Earth cover for the structures is also found to increase the
blast resistance. It is found that standard Navy heavy bomb-proof
structures with modifications can withstand a near-surface atomic burst at
ground zero. (T.F.H.)
