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.

The Monte Carlo technique has been used to determine some general properties of fast-neutron collimators for the cases in which the sources and detectors were finite disks. Based on these results, a collimator was designed to be used in determining the angular- and spatial-dependent neutron leakage spectrum from the TSF-SNAP reactor with a minimum distortion of the measured results. The detector-collimator response functions were then calculated for use in a separate Monte Carlo calculation of the leakage from the SNAP core. The adequacy of the response functions was determined by comparing the measured and calculated values of detector counts for a number of PoBe source locations off the axis of the collimator.
