| Abstract: | The
methodology, radiological safety planning and technical experiences gained
during the transfer of 1 mg of 252Cf neutron source from transport
container to exposure facility have been reported. Hot mockups with dummy
sources and radiation safety planning in advance have been observed as the main
contributing factor in personal dose reduction and to increase the confidence
level in radioactive source transfer in open condition. The doses received by
the personnel during this procedure are in the range 0.15-0.30 mSv, which are
well within the planned dose limit during operation (5 mSv). No accidental or
emergency situation had arisen during the course of this task. Before any new
high strength source expected to arrive in any institution, a full-scale mockup
should be performed to ensure all members of the work team to understand their
parts in the operation. Minimum possible persons should be involved in source
transfer. Too many minds at a time should not be applied in such a hazardous
operation. There should be only one supervisor at the site and no one except
the supervisor should be allowed to give instructions and suggestions during
the source loading or transfer procedure. Only expert and experienced radiation
safety personnel with high confidence level should undertake such operations.
All technical aspects and challenges faced during the source transfer have been
highlighted. |
