EV45 - PEP 2H: Status of ANSI N42 RPI & HSI standards (Cox)Lake Sheen B 10:30 - 12:30 |
| This summary covers the current status of American National Standards Institute (ANSI) N42 standards for health physics instrumentation in two sections: This section includes the discussion of some seventeen ANSI N42 standards for Radiation Protection Instrumentation (RPI) in effect, being revised or being combined, including those for performance & testing requirements for portable radiation detectors, in ANSI N42.17A for normal environmental conditions and in ANSI N42.17C for extreme environmental conditions, being combined; and now published ANSI N42.323A/B, for calibration of portable instruments over the entire range of concern, i.e., in the normal range and for near background measurements; performance criteria for alarming personnel monitors in ANSI N42.20; replaced airborne radioactivity monitors in ANSI N42.30 for tritium, ANSI N42.17B for workplace airborne monitoring, ANSI N42.18 for airborne effluent on-site monitoring, and ANSI N323C for test and calibration of airborne radioactive monitoring; instrument communication protocols in ANSI N42.36; in-plant plutonium monitoring in ANSI N317 is being revised; reactor emergency monitoring in ANSI N320 is being revised; quartz and carbon fiber personnel dosimeters in ANSI N322; installed radiation detectors in ANSI N323D needs to be updated and revised; ANSI N42.26 for personnel warning devices; radon progeny monitoring in ANSI N42.50 in development; and radon gas monitoring published in ANSI N42.51 by ARRP. The newly published ANSI N42.54 standard combines the salient materials for airborne radioactivity monitoring from ANSI N42.17B, ANSI N42.18 (airborne only), ANSI 323C and ANSI N42.30, with the comprehensive title of “Instrumentation and systems for monitoring airborne radioactivity”. This section includes the discussion of twenty ANSI N42 standards recently developed, being developed, or being revised and updated for Homeland Security Instrumentation (HSI), including those for performance criteria for personal radiation detectors in ANSI N42.32 that has been revised; portable radiation detectors in ANSI N42.33 in revision; portable detection and identification of radionuclides in ANSI N42.34; all types of portal radiation monitors in ANSI N42.35; for training requirements for homeland security personnel in ANSI N42.37 revised and published in 2017; spectroscopy-based portal monitors in ANSI N42.38 in revision; performance criteria for neutron detectors in ANSI N42.39, needing attention; neutron detectors for detection of contraband in ANSI N42.40, not addressed; active interrogation systems in ANSI N42.41; data formatting in ANSI N42.42, revised and updated; mobile portal monitors in ANSI N42.43; checkpoint calibration of image-screening systems in ANSI N42.44; criteria for evaluating x-ray computer tomography security screening in ANSI N42.45; performance of imaging x-ray and gamma ray systems for cargo and vehicles in ANSI N42.46; measuring the imaging performance of x-ray and gamma ray systems for security screening of humans in ANSI N42.47; spectroscopic personal detectors in ANSI N42.48; personal emergency radiation detectors (PERDs) in ANSI N42.49A for alarming radiation detectors and in ANSI N42.49B for non-alarming radiation detectors; backpack-based radiation detection systems used for Homeland Security in ANSI N42.53; portable contamination detectors for emergency response in ANSI N42.58 needing some attention; and ANSI N42.60 training for radiological/nuclear initial detection response, being developed. |
