ANS and the U.K.’s NI announce reciprocal membership agreement
With President Trump on a state visit to the U.K., in part to sign a landmark new agreement on U.S.-U.K. nuclear collaboration, a flurry of transatlantic partnerships and deals bridging the countries’ nuclear sectors have been announced.
The American Nuclear Society is taking an active role in this bridge-building by forming a reciprocal membership agreement with the U.K.’s Nuclear Institute.

As world communications improve, a common basis of understanding is essential. It is no longer sufficient to just make measurements, they must be internationally credible. The latest recommendations of ICRP, and the International Standard “evaluation of surface contamination Part 2 Tritium” are applied in practical terms, to achieve accredited measurements for the evaluation of tritium surface contamination. Three main requirements are explained. 1-A calibration reference source with certified emission rate. 2-A calibratable surface measuring instrument. 3-Reproducible measurements of all forms of surface activity.
