June 27, 2014 – Ottawa

Following a public hearing, the Canadian Nuclear Safety Commission (CNSC) announced today its decision to issue a Class 1B Nuclear Substance Processing Facility Operating Licence to Best Theratronics Ltd. (BTL). The licence will be valid from July 1, 2014, until June 30, 2019.

In making its decision, the Commission considered information presented at a May 8, 2014, public hearing in Ottawa, Ontario. During the public hearing, the Commission considered submissions from BTL and one intervenor, as well as CNSC staff’s recommendations.

The Commission concluded that BTL is qualified to carry out the activity that the licence will authorize. The Commission is of the opinion that BTL, in carrying out that activity, will make adequate provision for the protection of the environment, the health and safety of persons and the maintenance of national security measures required to implement international obligations to which Canada has agreed. CNSC staff shall provide the Commission with annual reports on BTL’s performance, as part of the CNSC’s annual performance reporting process for uranium and nuclear substance processing facilities.

The Record of Proceedings and Decision is available upon request by contacting the Commission Secretariat. It will be available, in both official languages, on the CNSC website at a later date. The transcripts of the hearing are available on the CNSC website at, or by contacting the CNSC. The webcast of the hearing is also archived on the same site, for a 90-day period.

The CNSC regulates the use of nuclear energy and materials to protect the health, safety and security of Canadians and the environment; to implement Canada’s international commitments on the peaceful use of nuclear energy; and to disseminate objective scientific, technical and regulatory information to the public.
