Taxis annex supplements Annex N of CJTF SEVEN OpPlan 3-53, the provisiens of which are applicable to all units of this command, b, Redielogical safety of all task force military end civilian perstnnel is @ commend responsibility end rediological safety activities will be performed tiorough normal command channels, ce. (1) Rediological Defense (RadDefense) operations, or Radiological Safety (RadSafe) operations, short term RedOps, are general terms, Tacy are used 6o denote the means by waicn a unit can control end confine the damage end vadisloglcal effects of an atomic explosicn, or ef radioactive materia). srreal by other means, thereby preventing and avoiding health hazcids to persunnel, They are interpreted to include such measures as training, organization, distritation of redielogicel personnel, develeprent of tcocnniques end procedures-for use of detecting equipment, protection or remuval of exposed personnel, and decontaiination cf personnel, structures and equiptcnt, (2) Following cach detonation there will be arena of surfece radiological contamination and areas of air radiological conteninatien,. These areas ere designated as Radielogical Exclusion Areas (dodex), Prier to shet tines, the forecasi air and surface Radex will be disseninsted by CUTF SEVEN in the target area, These iHadexes will represent a forecast fron HOW Hour (H-Hour) unvil dissenination of a later surface and air dedex at abeut Hd plus 4 hours, Tho later Hadexes will be besed upon the nestor radiological "situation map" maintained in the RadSefe Office of CJTF SEVEN, Since the air Hadex after shot tine will be based on nonitored air tracking by aireraft ever significant large ocean erers, inforuation promlgated fron the forecast air kedex may have to be extended beyond the originally anticipated 4-nour period, The surfece Hadex will be determined by actual survey with Hediation Detection, Indication and Cenputation (Radiac) equip~ ment efter shet tine, The nest rapid method of cecomplishing surfece survey in the early steges will ce by helicopter flight in and around the surfaces of contaminated areas, From the radiation intensities measured at a known altitude, it is possible to obtain on estimate of the radietion dosege rates whien would be encountered on the surface of the ground or water, Actual water samples from the lageen will also be utilized, Ground survey will follow these guides to determine definitely the contaminated regions and objeeta, Ge],
