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.

An on-line radioiodine monitoring system designed to operate under nuclear accident conditions is tested at the hot cell laboratory of a radiopharmaceutical production facility. The purpose of the work is to demonstrate that the patented Pennsylvania State University radioiodine monitor, using stabilized NaI(Tl + 241Am) detectors, can generate information about concentration of airborne radioiodine in real time. In the test of continuous iodine monitoring, the real-time 132I activities agree with those obtained by a high-purity germanium detector within a factor of ∼4. From the simultaneous operation of two monitors, one at the inlet and one at the outlet of the hot cell filter bank, the hot cell filter bank efficiency for the removal of airborne radioiodine is estimated to be at least 99.88%.
