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.

In a tritium handling facility it is important to know the volume of the parts of the system for accurate accountancy. The usual methods to determine volumes have several disadvantages concerning contamination issues and accuracy.In this work a novel method is used to determine volumes. The method does not require any liquid or precisely known reference volume. It is simple and the uncertainty of the measurement is lower than 1% for volumes from 10 cm3 to 10 dm3.In this paper the principle of the volume determination device (VDD) designed and built at the Tritium Laboratory Karlsruhe (TLK) is presented, together with a detailed uncertainty calculation. Also the first measurements with the VDD are discussed in detail.
