Collé has developed a body of technique for preparing and standardizing radon-222 gases and solutions, and has transferred this capability to national and international standards laboratories. Mann led the efforts among international standards laboratories to intercompare the Hönigschmid standards, and to base all the world's measurements of radium-226 on a common basis. Mann and Ronald Collé who have made numerous substantive contributions to radium measurements over the last fifty years.
