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 neutrino transport equation is nonlinear due to the Pauli exclusion principle. Enhanced absorption and spectrum hardening are typical phenomena stemming from this nonlinearity. The numerical methods used for the solution of the linear neutron transport equation were applied to the nonlinear neutrino transport equation. The sensitivity of the total energy leakage to the numerical parameters of a sample problem is presented in detail.
