Following the roll-up phase of Operation GREENHOUSE during late May and 

early June of 1,951, the only personnel remaining on Enewetak Atoll were a small 

military garrison and H&N @EC contractor) personnel. Radiation doses were 

previo&y calculated for Do0 personnel assigned to the residence islands of Enewetak 

during the operational phase of Operation GREENHOUSE In April and May of 1951 

(Reference 1). 7he purpose df this report is to provide an addendum to Reference I in 

which dose estimates are extended to include the military personnel who remained on 

Enewetak Atoll subsequent to the roll-up phase of Operation GREENHOUSE.

patrols (Referen& 5). The Air Force &it (the 493iit Test Support Squadron) provided 

air transportation within Enewetak Atoll with six L-13 aircraft. Most of the air

tit upcoming Operation IVY) on the northern islands of the atoll.

RESlDENCE l!XAND RADIATION ENVIRONMENTS 

. . . (. .._ 

Thb section describes the post-GREENHOUSE radiation environment on the 

res!dence islands of Enewetak Atoll. In Reference 1, island radiation environments 

were reconstructed based on numerous survey readings obtained dl.?-ing the operational 

phase of GREENHOUSE. Radiological decay rates used in dose .ycJ?ttructions for the 

operational phase were generally dictated by actual surveys +.a’~cvere approximately 

proportional to tB1*‘. It was assumed that these measure;: rates wrsisted from after 

the last survey through 31 May 1951, when the calculatio;:i ~-.:e :?rminatr,d. For the 

post-operational analysis, however, radiological surv\;y d..; ate nJt available and 

possible variations in the late-time (after 31 May) decay rates most be considered.

Table 3 gives the reconstructed Intensity (from XeZerence 1) on each of the 

residence islands ?n 31 May 1951, ksulting from fa!kou; from Shots DOG, EASY and

TOTAL 7.9 6.7 5.4 

The post-GREENHOUSE radiological environment on each of the islands is 

approximated using late-time decay rates suggested in Reference 6. For the first six 

months after each shot, radiological decay is proportional to t - 1.‘; thereafter, an 

6 
t y:“!’ accelerated rate proportional to tBLoL is considered appropriate. The intensities, 

Figure 2, are extended out to i Nov 1952, when Shot MIKE of Operation 

IVY was detonated on Enewetak Atoll. It is evident that even when “weathering” is 

neglected, natural ‘radioactive decay alone reduces the intensities to background levels

While -1.0 is taken as leading to an upper limit in dose, it is likely that an early 

deviation from tWLo2m. this direction was compensated by a faster decay after May 1.. 

1951. Given the additional tendency for fallout to partially leach into the ground

-1.4 surface, resulting in lesser measured gamma intensities, decay corresponding to t 

is considered as leading to a lower limit on dose. A similar uncertainty of + 0.2 in the 

decay exponent after six months is also used. These uncertainties are taken to apply 

systematically throughout the post-operational phase.

‘&door protection factor of 2 used in the dose determination is fairly representative of ’
