For holders of individual licences (L5, L6, R1, N3):
To amend your personal details (e.g. contact number, email address), please email NEA_RPNSD_Licence@nea.gov.sg with the current information to be amended and the updated information.
Which clinic should I go to get the medical check-up done?
Please bring the medical certificate form to a local medical clinic. The clinic will arrange for a blood test to be conducted. It will take a few days before the results are known. The doctor will follow up on your case, and complete the form before returning it to you. Please ensure that the doctor has indicated whether or not you are fit to engage in radiation work before you leave the clinic. You are advised to keep a copy of the medical form for your own reference. Please note that L5, L6 licences and R1 certificate holders in the NDT industry will need to undertake a blood test annually, and submit the test results to NEA during the renewal of the licences. This annual test is generally not compulsory for workers who are not in the NDT industry.
What other things do I need to know about radiation licences?
L5 / L6 licensees will each be issued with a TLD card for the monitoring of radiation exposure. Each new licensee will need to purchase a TLD card holder ($25.20). On a periodic basis, a new set of TLD cards will be issued. The L5 / L6 licensees are required to return their TLD cards and those of their workers (who hold the R1 certificate) to RPNSD for analysis. All previously issued TLD cards must be returned to RPNSD within two weeks upon the reception of new TLD cards. Note that a fee of $54.60 will be charged to the licensee for each loss/damage TLD card.
