Sealed Radioactive Sources (SRS) are wildly used in industry, agriculture, medicine, education and research. Because of some reasons, for example the radioactive content decay, the new technology application or the operator bankrupt, disused sealed radioactive sources (DSRS) will be produced and shall be managed well because the activity of some SRS and DSRS is still higher and the potential risks may happened. SRS and DSRS must be sustainably managed for the protection of individuals, society and the environment. DSRS management options usually include transfer to SRS producers/original suppliers, long term storage, disposal, reuse and recycle, exempt or clearance. In Ghana, some DSRS have been transferred back to SRS producers/original suppliers, DSRS that cannot be transferred back to SRS producer/original suppliers are been stored in related facility. Ghana is planning to carry on DSRS disposal project with other countries. The disposal options include near surface disposal, borehole disposal, or geological disposal. An optimized disposal option in Ghana shall be verified considering the total amount of DSRS, the radionuclides of radioactive content, the safety and economy of the disposal options and other factors. Among these factors, safety assessment on DSRS disposal must be carried out. Usually, the software AMBER or ECOLEGO is used for the safety assessment on DSRS disposal This research work seeks to layout of safety assessment of disposal options of DSRS. DSRS options comparison.
