MyCore Personnel

The staff of MyCore has extensive expertise in alpha spectrometry and in the application of this technique to ²¹⁰Pb analysis and radiometric dating. This expertise can be demonstrated in the ways that are listed below.

MyCore has performed many accurate and precise measurements of ²¹⁰Pb and ²¹⁰Po on standard reference materials (SRMs). These SRM measurements agree with the international consensus values and demonstrate that MyCore's measurements are consistent with other laboratories.
MyCore uses well-tested procedures in their lab work. These procedures have been used to analyze ²¹⁰Pb in more than 150 cores, with several thousand samples and related quality control samples during the past 4 years. These cores have come from a diversity of different environments; from the Canadian arctic to the high Andes Mountains. As a result of the diverse and extensive experience, MyCore staff can anticipate and resolve many problems that might occur before the analysis of an individual core is begun.
The principal scientist for MyCore, Dr Jack Cornett, has over 15 years of experience managing laboratories that perform radiochemical analyses including ²¹⁰Pb and ²¹⁰Po measurements.
The head of the radiochemical laboratory for MyCore, Ms Janice Lardner and her staff have 6 years of experience performing several thousand analyses of ²¹⁰Pb and ²¹⁰Po using the protocols that will be applied in the laboratory.
MyCore staff have published over 50 peer reviewed papers on various aspects of environmental chemistry and radiochemistry in scientific journals and they have made more than 100 invited technical presentations at international conferences and scientific workshops. These papers demonstrate that MyCore staff have continually developed new application ²¹⁰Pb dating and other radiochemical techniques in environmental science. Examples of specific publications and presentations on ²¹⁰Pb dating include:
