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.

Object scattering in thermal neutron radiography is described using analytically derived point and line spread functions. Applications in the response analysis for a knife-edged slab object have resulted in a new quantitative description of previously described edge scattering distortions that arise from unbalanced scatter. Experimental confirmation of the shape and relative magnitude of these distortions has been obtained. The inclusion of scattering effects in edge-location dimensioning prescriptions and the elucidation of the role of object scattering in the overall imaging system fidelity are presented.
