3. The source jacket drawings (Appendix 1) are offered by Party A. Party B can make modification to the sketch drawings according to the welding techniques, the Cobalt grain actual specific activity and the heat expansion dimension of the source jacket based on experience and simulation experiments, but the final drawing has to be approved by Party A.

4. The measurement of the radioactivity of the sources must be standardized. Considering the self-absorption of the sources and the revision of the measurement environment, the uncertainty of the measurement is limited within +/-10%.

5. The safety of the sources needs to be inspected according to GB18871-2002.

6. The service life of the sources is ten years and within the service life, no radiation leakage or contamination is allowed.

7. Party B must have fairly accurate measurement of the source outside diameter and constant temperature in a hot cave, for example, by the gauge inspection, etc.

8. Party B must clean and remove the rust from the source cell (“lift basket”) which transports the Cobalt-60 radiation sources used in SGS-I, and Party B should offer Party A the source loading and source acquisition procedure.

9. For the sealed source to be installed into the SGS-I, the arrangement of the sources in the source cell, and the coupling of the source cell with the lead container, are designed by Party A specially according to the registration data of the sources, which would be presented to Party B.
