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.

In order to recover tritium from light water, research and development was carried out concerning a tritium separation process based on the principle of hydrogen-water isotopic exchange reaction. The performance and durability of unit operations for the process were studied. A pilot plant having a capacity of 1 m3/year (3.6 L/day) was designed and fabricated based on the results of the tests and studies. Using this plant, tritiated water could be concentrated to the order of a magnitude of 104. Furthermore, the effect of the various operating conditions on the tritium concentration factor was calculated by applying a data analysis program for the pilot plant. This study offered the prospect of a practical application of the process by the hydrogen vapor isotopic exchange reaction to recovery of tritium from light water.
