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.

Thermal analyses for the U.S. inboard and outboard shield and first wall of ITER have been performed utilizing the nuclear heating results obtained from the neutronics calculations. Several radial build configurations of the shield have been thermally analyzed. Different routes for the coolant are investigated to reduce the maximum temperature in shielding material which in turn reduces thermal expansion effects during ITER operation. The maximum thermal stresses are within the prescribed limits for the shield material at the maximum operating temperatures.
