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.

The National Aeronautics and Space Administration (NASA) Radioisotope Power Systems (RPS) Program Mission Analysis Team at the Jet Propulsion Laboratory (JPL) requested a JPL Innovation Foundry Architecture Team (A-Team) study to assess mission pull for small RPS [1 to 40 W(electric)] and define the focus of future power system developments required to enable small RPS missions. The A-Team is JPL’s concurrent engineering design team for science definition and early mission concept development, targeting concept maturation levels of 1, 2, and 3. The requested small RPS study aimed to identify the architecture space of potential small RPS missions and suggest power levels that could enable or enhance potential future small spacecraft missions.
This technical note describes the collaborative engineering processes that the A-Team and Mission Analysis Team used to reach results quickly and presents the findings on power requirements for small RPS mission concepts.
