argon~alcohol) types. as a Future tests are required to retest dosimeters modified Ib is also apps result of Operation GREENHOUSE and to test promising new dosimeters, mo oF ed prior rent that more stringent laboratory testing of new modcls should be perform to actual field testing. moter was d. As in the case of the dosimeters,no particular type of survey found to be entirely adequate. Some types proved completely uscless but others be- haved excellently except for o few minor, correctible flaws, in general, the beta dctection capabilities of the various instruments were not satisfactory. This is be- lieved due to the lack of explicitness in the military characteristics which should be amplified so as to provide sufficient range and a reasonable degree of uniformity of sensitivity among the different instrument types. It is also recommended that Lat oratory test facilities be extended to simulate various climatic conditions, e. Operation of the mobile radiological ficla Laboratory threw a light on a number of important factors, The original designs and proccdures wore too sweeping in scope to allow for efficient ficld laboratory operation, The Inboratory should ave been designed and equipped to perform a few specifie proccdures adequately. Instead, the procedures were developed after the field laboratory was physically in existence, During the period of operation, procedures were develooed which in effect provided the type of information required for laboratory analysis. On the basis of these procedures, as well as on the findings reported from tests performed on the precurser to the present model of the field laboratory, certain modifications wore found to be desirable, These modifications limited the scope of the ficld laboratory but stressed procedures which yielded the maximum of useful information and so, inereased the efficiency of operations, It was found necessary to augment the equip- ment supplicd, both electronic and chemical, some of the equipment originally supplied, It was also found necessary to remove Future operations and tests are requircd - to indicate necessary further developments and modifications. f. The results of the Laundry monitoring will be reported on in more de- tail in the final report but early results indicate thet present proccdures are not entirely satisfactory, 3« .
