Scope This standard defines, for various types of instrum

This standard does not specify which of the instruments or systems are required nor does it consider the number o

For the purpose of this standard, the predominant consideration in the assessment of radiation emergencies is the measurement of fission products

Where instruments utilized for routine op- erations fulfill the criteria herein, they need not be duplicated in order to have separate emergency instrumentation. Dual purpose in- strumentation must meet the requirements of this standar

Such plans must include the provision of adequate radio- logical instrumentation to detect and quantify and the word may to denote permission, neither a requirement nor a
38、 recommenda- tion. It is important that instruments, systems, or individual components intended for emergency application be: (1) Qualified for use under extreme condi- tions (2) Preoperationally tested over the entire range of operation (3) Periodically checked and calibrated ac- cording to an appr
39、opriate calibration program The criteria herein apply only to instru- mentation installed or located at the reactor facility and intended for use by facility person- nel in the conduct of emergency operations. Instrument selection will of necessity be deter- mined on a case by case basis considering
40、 in- dividual facility emergency plans and site specific parameters. These plans involve sev- eral elements including measurement of mete- orological parameters, establishment of com- munications, arrangement for off-site work support personnel, identification of capabil- ities, capability of detect
