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.

A numerical method for the calculation of the radial and axial diffusion coefficient for the hexagonal lattice of a high-temperature reactor with block elements is developed. Results for a typical lattice are given and a comparison with the formulas of Behrens and Benoist is made. A modification of Benoist's formulas for a tightly packed lattice that gives a better agreement with the numerical results is proposed.
