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.

We discuss the technology developed at the Lebedev Physical Institute for the manufacture of hollow microspheres polyethylene terephthalate (PETP). The microspheres are produced by means of foaming solid PETP granules containing CO2 blowing agent in a vertical free-fall furnace. The diameter of obtained microspheres ranges from 50 to 800 µm, with aspect ratio typically from 10 to 50. Reasonably high maximum rupture strengths and relatively low permeabilities have been measured. These properties allow PETP microspheres to be used for long-duration storage of gases and in the technology of cryogenic targets for the ICF program.
