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.

A production route for 99mTc and 101Tc using the (γ,p) reaction was considered. For an electron beam with energy of 40 MeV and power of 10 kW, distributions of produced 99mTc and 101Tc were obtained. For the optimized target (0.5 g) configurations, values of 99mTc specific activities of 9.53 GBq/g (0.26 Ci/g) for a one-stage setup and of 1.77 GBq/g (0.049 Ci/g) for a two-stage setup were obtained. For 101Tc, the corresponding values were 6.51 GBq/g (0.18 Ci/g) and 1.24 GBq/g (0.033 Ci/g).
