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.

JAERI started a program of Demonstration Poloidal Coils (DPC) for superconducting pulse poloidal coils. In this program, two NbTi pulse coils, DPC-1 and DPC-2, and a Nb3Sn pulse coil, DPC-EX are being developed. These coils have the same diameter of 1.0 m and the charging condition is from zero to 7 T in 1 sec. Total stored energy of DPC-1 and DPC-2 will be 30 MJ. Regarding design requirements and conditions of DPC, design selections on the coil configuration, charging mode and insulation, cooling type, conductor, and so on were made as described in this paper.
