Ronald Collé (born February 11, 1946) is a specialist in nuclear and radiochemistry, radionuclidic metrology, and the development of standards.
[1] Previously, he held research positions at Brookhaven National Laboratory,[2] and at the University of Maryland, College Park.
[4][5] Collé and collaborators developed methods to analyse and standardize brachytherapy sources, pellets of radioactive material designed to be implanted in the body at site requiring direct radiation exposure.
[6][7] An important part of metrology and standards development is understanding and taking into account uncertainties that are inherent in the instruments or that arise from methodology.
Collé co-authored a paper with Churchill Eisenhart and Harry Ku,[8] which was the forerunner of the 1993 ISO Guide to the Expression of Uncertainty in Measurement.
