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.

Improved multicollision neutron fluence-to-dose conversion factors have been calculated for a phantom exposed to neutrons with energies from 15 MeV down to thermal. The phantom was a 30-cm-thick slab composed of the 11 most common elements in the standard man. The calculations consisted of the simultaneous solution of the neutron and secondary gamma-ray transport problem with the ANISN computer code for both a beam source and an isotropic flux source, and for a slab having both infinite and finite transverse dimensions. The fluence-to-dose conversion factors were based on new neutron fluence-to-kerma factors and improved secondary gamma-ray yields determined for the individual elements comprising the slab. The neutron and gamma-ray cross sections used in the calculations are from the ENDF/B file and the OGRE library, respectively.
