Ronald Collé (born February 11, 1946) is a specialist in nuclear andradiochemistry, radionuclidicmetrology, and the development of standards. He has worked at theNational Institute of Standards and Technology (NIST) from 1976 to 2003 and from 2005 to present, and currently serves as a research chemist in the Radioactivity Group of the NIST Physics Laboratory (Ionizing Radiation Division).[1]
Previously, he held research positions atBrookhaven National Laboratory,[2] and at theUniversity of Maryland, College Park.[3] He received a B.Sc. in chemistry from theGeorgia Institute of Technology in 1969, a Ph.D. in chemistry (nuclear and radiochemistry) fromRensselaer Polytechnic Institute in 1972,and an M.S. Adm. (Administration of Science and Technology) fromGeorge Washington University in 1979.[1]
Collé and his collaborators have maintained, expanded and improvedradioactivity measurement standards forradium-226 andradon-222 to address the requirements to measure thesenuclides indrinking water.[4][5] Collé and collaborators developed methods to analyse and standardizebrachytherapy sources, pellets of radioactive material designed to be implanted in the body at site requiring direct radiation exposure.[6][7]
An important part ofmetrology 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 withChurchill Eisenhart and Harry Ku,[8] which was the forerunner of the 1993ISOGuide to the Expression of Uncertainty in Measurement.[9]
Collé has published over ninety research papers, and from 1999 through 2004 was an associate editor of theJournal of Research of the National Institute of Standards and Technology.[10]
