The RAIN scale: A good intention that falls short
Radiation protection specialists agree that clear communication of radiation risks remains a vexing challenge that cannot be solved solely by finding new ways to convey technical information.
Earlier this year, an article in Nuclear News described a new radiation risk communication tool, known as the Radiation Index, or, RAIN (“Let it RAIN: A new approach to radiation communication,” NN, Jan. 2025, p. 36). The authors of the article created the RAIN scale to improve radiation risk communication to the general public who are not well-versed in important aspects of radiation exposures, including radiation dose quantities, units, and values; associated health consequences; and the benefits derived from radiation exposures.

The main three subsystems of the ITER Tritium Fuel Processing Plant, the Tokamak Exhaust Processing (TEP) System, the Isotope Separation System (ISS) and the Storage and Delivery System (SDS), are equipped with enough instrumentation to control the various processes. In addition to this system-dedicated instrumentation, a central facility called Analytical System (ANS) has been designed for i) verification and determination of the composition of the various gas mixtures processed in the Tritium Fuel Processing Plant and ii) checking and monitoring the local equipment. The analytical requirements of the subsystems of the ITER tritium plant are summarised. A comparison of various analytical techniques revealed that gas chromatography is the most suitable method. The design of the Analytical System comprising three micro and two conventional gas chromatographs and its safe operation are discussed in detail.
