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.

Using the weighted least-squares fit of the curve count rate versus time, we have measured the half-life of 165Dy and found its value to be 140.02 ± 0.36 min. This value was checked by measurements of thermal-neutron flux using a dysprosium foil, assuming a number of values of T1/2 clustered around the previously determined value.
