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.

This paper presents experiments carried out to study the influences of transverse vibration on horizontal gas-liquid two-phase flow. The experiments considered the transverse vibration over a wide range of vibration frequencies and vibration amplitudes. Five typical flow regimes were observed. The fluid flow conditions in steady state and transverse vibration were compared. The traditional flow regime transition lines did not match the gas-liquid flow in channel under transverse vibration. The results suggest that vibration frequency mainly affected the flow regime by promoting the aggregation of gas slug, while vibration amplitude mainly influenced the fluctuation height of the gas and liquid interface.
