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.

Neutron spectrum measurement based on the foil activation technique was carried out as a part of the JAERI/USDOE collaborative program on fusion blanket neutronics. The adequacy of the foil activation technique and the current dosimetry nuclear data for the D-T fusion neutron field were examined through the analysis of the spectrum in a Li2O blanket system enclosed with the Li2CO3. A method using a pair of activation indices (MPI) is newly proposed to evaluate the neutron flux around the MeV region of interest in a qualitative way. The multi-foil activation technique (MFA) with proper detector cross section data are promising to determine neutron spectra over a wide energy range.
