qari Joint Task Force SEVEN Task Group 7,3: Eniwetok Atoll, M.I. a+ Operation Plan CTG 7.3 No, 1-53 8 April 1954, 1800M Appendix IV to Annex G Radioactive Fallout Reports 1. For one week following each shot each ship shall report radioactive fallout encountered as follows: a. A report shall be made of fallout readings (gamma only) of 1 mr per hour or higher. b. Only the vaiue of gamma radiation shall be reported. c. Reports will be coded as follows: Rabbit" followed by a number to indicate average topside activity, the number indicating mr per hour (gamma only); "Cat" followed by a number to indicate maximum activity found on the ship, the number indicating mr per hour (gamma only). Thus a message "Rabbit: 2 Cat 7" indicates the averege topside activity is 2 mr per hour (amma only), and the maximum activity found on the ship is 7 mr per hour (gamma only). Fractional numbers will be reported as the nearest whole number, Thus if the average topside activity is 3.8 mr per hour (gamma only) and the maximum activity found on the ship is 8.4 mr per hour (gamma only) the message to be sent is "Rabbit 4, Cat 8", ad. New reports shall be made when the averege topside activity increases to more than twice that last previously reported or decreases to less than half that last previously reported. e. Reports shall be sent by radio or light to CTG 7.3, to the USS BAIROKO, and to the USS ESTES. These reports shall be delivered to the RadSafe Center on the BAIROKO end to the RadSafe Office on the ESTES, f, Reports shall be sent on TG 7.3 UHF Admin or C¥ Common or on TG 7.1 Pogo or Admin Nets, as appropriate. g. One week after each shot every ship shall send to CTG 7.3 a complete letter report on radioactive contamination experienced since the shot occurred. As applicable, each letter shall include a table with estimated average intensity topside in milliroentgens per hour and approximate position of ship in latitude and longitude at fallowing times: Hourly on the hour from How hour to 2000M Dog day; every four hours from 2000i Dog day to OLO0CM Dog plus two day; daily at O800M Dog plus two yO G-IV-1 CHANCE #4,
