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.

At the LOTUS facility, an extremely efficient online detector system, based on the detection of the charged particles associated with the 6Li(n, α)t reaction, has been designed, fabricated, and tested. The system offers an interesting possibility for directly measuring the tritium production rate (TPR) at any experimental site. The charged particles emitted in opposite directions can be detected by a double parallel plate ionization chamber (DIC) configuration. The real events are identified by employing a coincidence circuit. The complete fabrication details, testing under different conditions, measurement of TPR, and its comparison with the liquid-scintillation method (LSM) are detailed. The DIC response to thermal neutrons agrees well with the theoretical calculations. Also, the detector system is insensitive to a contact gamma dose rate of 1.3 rem/h. The direct TPR measurements and the salient feature of higher efficiency in comparison with the LSM are demonstrated. The TPR determined by both methods are in excellent agreement.
