A.G.T. has been awarded three new purchase orders from Concord Steel Centre Ltd. (Woodbridge, ON) to address the upcoming decertification of Weston 5310 isotope sources in Canada. The Canadian Nuclear Safety Commission (CNSC) has advised that certification of these sources, used on non-contact thickness gauges, will expire January 31, 2017. The purchase orders cover the following actions: 1) Removal, packing, leak testing and transfer to A.G.T. of two 5310 sources currently in use at Concord; 2) Replacement of an obsolete Loral 3500 isotope thickness gauge with a new AGT800 laser thickness gauge; and 3) Replacement of a 5310 source with a new AGT400 Am241 source head assembly which has already been recertified for use in Canada by the CNSC.
