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.

To investigate the feasibility of applying a porta-ble neutron generator for neutron radiography (NR), an underwater NR facility was designed and constructed in the water pool in a hot laboratory. By using the system, including neutron converters and films, it was possible to obtain NR images within ∼10 min. Various characteristic tests and photography by both emulsion and tracketch methods were carried out for various objects containing irradiated nuclear fuel samples. Some combinations of the converter and x-ray films, such as gadolinium foil/Type AA, were found to be suitable for NR in this case, but the much more sensitive converter NE426 was able to reduce the exposure time considerably. The strongly irradiated nuclear fuel samples were successfully photographed by CA-8015 track-etch films with a 10BN converter.
