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.

Techniques for forming a beam of negative molecular ions by attaching electrons to molecular gases are discussed and a conceptual design for a quasi-continuous source is given. Performance estimates show that a concept demonstration could be performed using currently available excimer lasers to create a population of free electrons by photoionizing xenon. Scaled-up ion sources yielding tenths of amperes will be practical if more efficient excitation schemes can be developed.
