= X-Ray-minus-two the film badges and heat sensitivity materials were placed on the islands adjacent to Engebi. During this period the panels and plaques to be used for studying thermal radiation were installed and covered to prevent exposure to rain. On the morning of X-Ray-minus-one, four members of TU 7.6.6 went ashore on Engebi to place biological materials in cans, to remove covers from heat sensitive plaques and to install filmbadges and heat sensitive papers on exposed stakes, These materials would be used for measurement of the nuclear and thermal radiation as a function of distance, Distribution was carried out without difficulty and final preparations for test X-Ray were completed by noon on X-Ray-minus-one, The following is a list of projects carried out under TU 7.6.6: DELETED AEA Restricted Data Project 7.1-17/RS-1 - Gamma Radiation vs Distance AEA Restricted Data 82
