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.

Radial particle transport in GAMMA 10 was investigated under a quasi-steady state condition plasma. The transport analysis was carried out with changing the boundary conditions, in order to reconstruct the density profile which is consistent with the measured data. From the above result, the best fit profile to the measured one was obtained with the diffusivity of 0.57 m2/s. The particle diffusivity in an additional gas puffing experiment was estimated. The result of the transport analysis was also compared with the diffusion coefficient expected from classical diffusion processes.
