Dear Dr. Corriveau:
 
It was a pleasure to meet with you last May 25 to discuss our group's concerns about tritium emissions from SRB Technologies (Canada) Inc. We appreciate your willingness to share information and views.
 
Since meeting with you in May, we have received reports on vegetation samples that we had analyzed for tritium content by the Environmental Isotope Laboratory at the University of Waterloo, and by Becquerel Laboratories in Missisauga, Ontario. A rhubarb sample collected from a garden 800 m downwind from SRB had a tritium concentration of 2000 Bq/L free water, and a control sample taken near Golden Lake had a tritium concentration of 2 Bq/L. A sample of aspen leaves collected about 50 m behind the plant had a tritium concentration of 1890 Bq/L free water. The latter sample had a larger concentration of tritium than any of the aspen leaf samples analyzed by Robert Brown of AECL in his 1978 study of environmental tritium in trees in the vicinity of the Chalk River Nuclear Laboratories.
 
We believe that this level of contamination is unacceptable and we have written to SRB General Manager Stephan Levesque to request that SRB install a pollution control device to virtually eliminate environmental releases of tritium. We have also written to Dr. Agnes Bishop of the Atomic Energy Control Board requesting that installation of such a device be made a condition for re-licensing of SRB later this year. Your copies of these letters are enclosed.
 
Sincerely yours,
Ole Hendrickson, Ph.D.
