CG-47级船只有几种能够赋予高水平的RF能量的雷达系统。持续超过10 MW / SQ CM的持续RF功率密度被认为对人员有害。海军正在考虑采用ANSI C95.1-1982的更严格的Radhaz标准。CG-47级船舶中使用的一些元素易于RF能量的影响。3.通过人员访问限制，辐射区控制，输出功率控制和维护安全分离距离，可以防止Radhaz和英雄问题。各种雷达系统设计中固有的控制特征，具有严格的程序实现，可以提供有效的RF安全性，操作撞击最小。 4. THE FOLLOWING PRECAUTIONS SPECIFY RADAR MAIN BEAM RADHAZ SAFE DISTANCES FOR BOTH THE 10 MW/SQ CM CRITERION AND THE MORE STRINGENT ANSI CRITERIA. RADHAZ SAFE DISTANCES FOR THE ANSI CRITERIA SHOULD BE USED WHEN OPERATIONALLY FEASIBLE. 5. RADHAZ PRECAUTIONS INPORT: A. AN/SPY-1A. HIGH POWER OPERATION SHALL BE IN THE MAINTEN- ANCE MODE UNDER LOCAL CONTROL ONLY. THIS MODE PLACES THE BEAM AT THE ZENITH POSITION. NESTED SHIPS SHOULD BE ADVISED TO KEEP PERSONNEL MORE THAN 45 FEET FROM ARRAY FACES AND BELOW LEVELS EQUIVALENT TO 23 FEET ABOVE ARRAY (APPROXIMATELY TOP OF FORWARD DIRECTORS AND TOP OF NUMBER 3 DIRECTOR AFT). PERSONNEL MUST BE WARNED NOT TO LEAN OVER RAILS ABOVE THE ARRAY FACES. THE HELICOPTER LIGHTING MAINTENANCE PLATFORM ALLOWS PERSONNEL ACCESS TO A RADHAZ ZONE DIRECTLY IN FRONT OF THE AFT ARRAY FACE. THE ACCESS IS NORMALLY BARRICADED, BUT STRINGENT PROCEDURAL CONTROLS MUST BE IMPLEMENT- ED TO PREVENT PERSONNEL FROM INADVERTENTLY ACCESSING THE AREA WHEN THE RADAR IS ACTIVE. IN LOW POWER OPERATION, THE MAIN BEAM MINIMUM SAFE DISTANCE IS 30 FEET (50 FEET USING ANSI CRITERIA). B. FIRE CONTROL SYSTEM MK 99. EXTERNAL CW ILLUMINATOR RADI- ATION MUST ALWAYS BE UNDER CONTROL OF C&D: E.G., SIMULATED ENGAGE- MENT. THE BEAM MUST NOT BE DIRECTED TOWARD ANY SHIPYARD OR SHIP STRUCTURE, I.E., CRANES, BUILDINGS, TOWERS AND ADJOINING SUPERSTRUC- TURES. BY SELECTIVE TARGET DESIGNATION IN CLEAR AREAS AUTHORIZED BY THE SHIPYARD SUPERINTENDENT, LIMITED ILLUMINATOR OPERATION CAN BE ACCOMPLISHED. THE ILLUMINATOR GENERATES HAZARDOUS MAIN BEAM RF LEVELS OUT TO 1310 FEET (1850 FEET USING ANSI CRITERIA). C. EW SYSTEM AN/SLQ-32(V)3. THE SLQ-32 SYSTEM SHALL HAVE THE TRANSMITTER OUTBOARD SPECIAL TEST EQUIPMENT (TOSTE) INSTALLED TO SUPPRESS RADIATION WHILE OPERATING INPORT. D. RADAR SYSTEM AN/SPS-49. SPS-49, WHILE ROTATING, DOES NOT CREATE ANY RADHAZ AREAS, BUT EMI EFFECTS TO COMMERCIAL TV AND RADIO RECEIVERS MAY LIMIT ITS USE INPORT. CONTACT THE SHIPYARD SUPERINTENDENT PRIOR TO OPERATION. IF SPS-49 IS RADIATING WITH THE ANTENNA STATIONARY, THE MAIN BEAM MINIMUM SAFE DISTANCE IS 200 FEET (440 FEET USING ANSI CRITERIA). E. RADAR SYSTEM AN/SPQ-9A. DURING NORMAL OPERATION WITH THE ANTENNA ROTATING, SPQ-9A DOES NOT CREATE A RADIATION HAZARD. IF SPQ-9A IS RADIATING WITH THE ANTENNA STATIONARY, THE MAIN BEAM MINIMUM SAFE DISTANCE IS 65 FEET (85 FEET USING ANSI CRITERIA). IN THIS MODE THE ANTENNA SHALL BE DIRECTED ONLY TO CLEAR AREAS AS AUTHORIZED BY THE SHIPYARD SUPERINTENDENT. F. CLOSE IN WEAPON SYSTEM (CIWS). CIWS SHALL BE DIRECTED ONLY TO CLEAR AREAS AS AUTHORIZED BY THE SHIPYARD SUPERINTENDENT. IN THE TRACK MODE, THE BEAM GENERATES HAZARDOUS MAIN BEAM RF LEVELS OUT TO 90 FEET (140 FEET USING ANSI CRITERIA). G. RADAR SYSTEM AN/SPS-55. DURING NORMAL OPERATION WITH THE ANTENNA ROTATING SPS-55 DOES NOT CREATE A RADIATION HAZARD. IF SPS- 55 IS RADIATING WITH THE ANTENNA STATIONARY, THE MAIN BEAM MINIMUM SAFE DISTANCE IS 25 FEET (50 FEET USING ANSI CRITERIA). H. AN/WSC-3 SATCOM. WSC-3 CAN CREATE HAZARDOUS RADIATION LEVELS OUT TO 4 FEET FROM THE WSC-1 ANTENNA (15 FEET USING ANSI CRITERIA). I. LN-66. LN-66 DOES NOT PRODUCE HAZARDOUS RADIATION LEVELS USING THE 10 MW/SQ CM CRITERION. HAZARDOUS LEVELS EXIST OUT TO TWO FEET FROM THE ANTENNA IF ANSI CRITERIA ARE USED. J. OTHER RADIATION RESTRICTIONS MAY BE SPECIFIED BY THE PAR- TICULAR PORT OF CALL. ADVANCE CONTACT WITH PORT AUTHORITIES SHOULD BE ESTABLISHED. 6. RADHAZ PRECAUTIONS AT SEA: A. RADHAZ SAFE DISTANCES. MAIN BEAM RADHAZ SAFE SEPARATION DISTANCES SHOWN BELOW MUST BE MAINTAINED IN A MULTIPLE SHIP ENVIRON- MENT. RADIATING ELEMENTS NOT SHOWN DO NOT CREATE RADHAZ CONDI- TIONS BEYOND THE SHIP BOUNDARIES IN THEIR NORMAL OPERATING MODES. RF SOURCE MINIMUM SAFE DISTANCE 10 MW/SQ CM CRIT. ANSI C95.1-1982 CRIT. AN/SPY-1 (HIGH POWER) 360 FT 520 FT AN/SPY-1A (LOW POWER) 30 FT 50 FT AN/SPG-62 (FCS MK 99) 1310 FT 1850 FT AN/SLQ-32 90 FT 130 FT CIWS 90 FT 140 FT B. MAN ALOFT. ALL AREAS ABOVE THE 05 LEVEL AND THE HELICOPTER LIGHTING MAINTENANCE PLATFORM ON THE 04 LEVEL ARE MAN ALOFT AREAS. PROCEDURES SHALL BE ESTABLISHED TO ENSURE RADAR AND RADIO TRANSMITTERS FOR THESE AREAS ARE SECURED WHILE MEN ARE ALOFT. C. WEATHER DECK. THE 03 LEVEL FORWARD OF THE AN/SLQ-32 AND THE BOAT STORAGE AREAS AFT OF THE AN/SLQ-32 ARE HAZARDOUS WHEN THE ACTIVE EMITTERS ARE RADIATING. PERSONNEL SHOULD BE RESTRICTED FROM THESE AREAS WHEN RADIATION IS POSSIBLE. AREAS OF THE BRIDGE WINGS ARE EXPOSED TO RF LEVELS WHICH EXCEED THE ANSI CRITERIA, BUT ARE LESS THAN 10 MW/SQ CM, DURING TRANSMISSION BY THE 10-30 MHZ TWIN WHIP ANTENNA ATOP THE PILOT HOUSE, ANTENNA 2-3. THE HAZARD CAN BE MINIMIZED BY LIMITING HF TRANSMITTER POWER TO 500 WATTS OR BY RE- STRICTING ACCESS TO THE BRIDGE WINGS DURING TRANSMISSION BY THE TWIN WHIP. 7. HERO PRECAUTIONS: A. CIWS. CIWS IS CONSIDERED HERO SUSCEPTIBLE IN SEVERAL FRE- QUENCY RANGES. THE HERO RESTRICTIONS ARE SPECIFIED IN OP 3565 ADVANCED CHANGE NOTICES 4/3, 15/3, AND 19/3, REFERENCES A, B AND C RESPECTIVELY. HERO RELATED AMMUNITION HANDLING PRECAUTIONS FOR CIWS ARE PROVIDED IN REFERENCES A AND D. CIWS HERO RESTRICTIONS ARE SUMMARIZED BELOW. (1) TOUCHING OF THE 20MM ROUND PRIMER SHOULD BE AVOIDED AT ALL TIMES. DURING OPERATION REQUIRING ON DECK HANDLING OF BARE (WITHOUT RADHAZ LINKS) 20MM ROUNDS, TRANSMITTERS IN THE 2 MHZ TO 1400 MHZ FREQUENCY RANGE SHOULD BE SECURED. (2) WHEN TRAVELING IN COMPANY WITH OTHER SHIPS, PRE- CAUTIONS SHOULD BE TAKEN TO AVOID DIRECT ILLUMINATION OF 20MM AMMUNITION (ON DECK, IN LOADERS OR MOUNTS) WITH FIRE CONTROL OR SURFACE/AIR SEARCH RADARS IN THE 2.7 GHZ TO 8.4 GHZ FREQUENCY RANGE WITHIN THE SPECIFIED SAFE DISTANCES. SAFE DISTANCES ARE SPECIFIED IN REFERENCES A AND B. THIS RESTRICTION APPLIES TO RADIATION OF CG-47 CLASS SHIP CIWS BY OTHER SHIPS AND TO CG-47 CLASS SHIP RADIATION OF OTHER SHIPS CIWS. THE SAFE DISTANCE SPECIFIED IN REFERENCE B FOR AN/SPY-1A IS 1462 YARDS. THERE ARE NO RESTRICTIONS ON ILLUMINATION OF THE MOUNT IF LIVE AMMUNITION IS TOTALLY CONTAINED WITHIN THE DRUM MAGAZINE. (SEE REFERENCE C FOR DETAILED INSTRUCTIONS). B. SRBOC. AN/SLQ-32 RADIATION SHOULD BE INHIBITED WHEN CON- DUCTING SRBOC HANDLING AND LOADING OPERATIONS. C. STANDARD MISSILE 1 (SM-1). SM-1 IS CONSIDERED HERO SUSCEPTIBLE AND SHOULD NOT BE EXPOSED TO MAIN BEAM HIGH POWER ILLUMINATION BY THE AN/SPY-1A PRIOR TO LAUNCH. D. ASROC. ASROC CONFIGURED WITH ISA MK 4 MOD 0 IS HERO SAFE AND THERE ARE NO HERO RESTRICTIONS ON OPERATIONS WITH THIS MISSILE. ASROC CONFIGURED WITH ISA MK 3 MOD 2 IS HERO SUSCEPTIBLE AND SHOULD NOT BE EXPOSED TO MAIN BEAM HIGH POWER ILLUMINATION BY THE AN/SPY- 1A OR TO MAIN BEAM ILLUMINATION BY THE AN/SPG-62. ADDITIONALLY, HF TRANSMISSION BY THE 10-30 MHZ TWIN WHIP ANTENNA ATOP THE PILOT HOUSE SHOULD BE DISCONTINUED DURING HANDLING, LOADING OR PRESENCE OF ASROC CONFIGURED WITH ISA MK 3 MOD 2 IN THE VICINITY OF THE FORWARD GMLS MK 26 LAUNCHER. 8. HELICOPTER OPERATIONS - FOUR PROBLEM AREAS MUST BE CON- SIDERED: RADHAZ - ELECTROMAGNETIC RADIATION FROM THE SHIP'S SENSORS COULD BE SUFFICIENTLY INTENSE TO CREATE A RADIATION HAZARD TO THE HELICOPTER AIR CREW. HERO - ELECTROMAGNETIC RADIATION FROM OWNSHIP RADARS MIGHT TRIGGER THE DETONATION OF ORDNANCE AND PYROTECHNICS ON THE HELI- COPTER. EMI/EMC - FRIENDLY JAMMING COULD RESULT FROM INTERFERENCES BETWEEN THE SHIP AND HELICOPTER SENSORS. INTERCEPT BY OWNSHIP WEAPONS - THE HELICOPTER COULD BE INTER- CEPTED BY OWNSHIP WEAPONS EITHER AS A RESULT OF BEING INADVERTENTLY INTERCEPTED BY A WEAPON INTENDED FOR A THREAT PLATFORM OR A RESULT OF BEING IMPROPERLY DECLARED A HOSTILE TARGET. A. PEACETIME, NON-OPERATIONAL EXERCISES GREATLY REDUCE THE PROBLEMS. WEAPONS SHALL BE SECURED AND SENSORS INHIBITED OR RE- DUCED TO LOWER OUTPUT POWER SO THAT CONVENTIONAL RECOVERIES AND LAUNCHES MAY BE ACCOMPLISHED. B. UNENGAGED OPERATIONS CONSTITUTE ANY OPERATIONAL ENVIRON- MENT WHEN THE SHIP IS NOT DEFENDING ITSELF. IF AN ATTACK IS IMMINENT OR EVEN POSSIBLE (WARTIME CONDITIONS), IT WILL BE NECESSARY TO LIMIT THE PERIOD OF TIME DURING WHICH THE OPERATION OF SENSORS WOULD BE INHIBITED TO THE SHORTEST TIME POSSIBLE. C. RECOVERY AND LAUNCH OPERATIONS DURING AN ACTIVE ENGAGE- MENT ARE NOT RECOMMENDED; BUT SHOULD AN EXIGENCY ARISE, COMMAND DECISIONS MUST BE MADE USING RISK TRADEOFFS, E.G., DIVERSION OF HELICOPTER TO ANOTHER PLATFORM, HOLDING PATTERN. EACH AEGIS SHIP SHALL DEVELOP A DOCTRINE FOR HELICOPTER OPERATIONS IN VARIOUS COMBAT POSTURES. 9. THIS INFORMATION WILL BE INCLUDED IN THE AEGIS CSTOM.
