Their Suppers requirexents were scusuhat modest in comparison with those of Project 1.4 and they were able to maintain their stations in readiness for the shosa, in spite of the excvscive delays in the abote, with the ascigument of one spsoially modified Loh, in general, Program 1 wae able te acoomplish ita assigusd mission. The croral? results obtained by Frogran 1 were sasewhat lecs than had been enticipated dus to the extreme variation in yields of several shots, the cancellation of one shot and the change in the Zoontion of several of the vhote.

In Progran’2, measures uente were nade of the tote! gmama radiation on ali shots ant the . gana rediation versus time on three shots, neutron flux and speo~ trum on 3 shots and fall out on all shots. Meneurements of total gamma presented ne unuscal operational prevlems since these measuresents were made by neans of conventional fils badge dosimetry, The equipment for meaguring the ganem rate aa a function of tim functioned satisfasterliy on the first shot, however, the extremly high yield of this shot net only damaged nany of the measuring sta-~ tions but alee caused a fire in the adainistrative compound on Tare which destroyed a large proportion of tho projects spare equipment. For this reasen, participation in succeeding shots was extremly lisited and very few stations were activated, The neutron measuree monts were reasonably suseesaful on the first two shots although considerable damage was dene to the close-in statione and residual contunination prevented early recovery, thus decreasing the usefulnese of the information, The fall out program presented the most difficult operational problem in the effects program. , Fall out measurements were made in three genere] areas; within the lagoons, en evallable land masses and in the open sea. Measurements within the lagoon vere made by means of anchored floating raft stations equipped with approprinte collector devices, The extremly rough . water of Bikini lagoon resulted in the loss of a mumber of etations even befors the firat shot due to an unsaticfactory anchoring arrangement. The high yield of the Mrst ehct overturned many of the rafte, thus destroying thelr usefullness for collecting fall out ~S42- , as a i asta me Po ~coe# yA
