For the purpose of demonstration, workshops or trials, the apparatus must be authorised under a possession licence (L3 / N2) if the apparatus is to be energised. There is no restriction that the licence holder would have to be either the client or the vendor. However, the licensee should note any licensing conditions that may be imposed (e.g. vendor representative may be required to be present for use of the apparatus).

As licence holders are directly responsible for the apparatus under their licence, the responsibility would be on the licensee to amend the storage location should they wish to relocate the apparatus. For relocation from one storage location back to a previously used storage location again, licensees should include a note in the amendment application stating that location has been used before to store the apparatus and provide details such as last inspection date (if available). If the storage location that it is being moved to was once inspected before, additional inspection might not be necessary to facilitate the amendment.

In cases where the apparatus owned by a vendor is intended to be moved to various customers’ premises for short term use (e.g. cases where apparatus is used for trial, demonstration, training purposes, etc.), having the vendor as the licence holder could be more convenient in terms of licence-related work. For each move, the vendor would be able to apply for licence amendment; as opposed to each customer applying for a new licence each time.

If the apparatus would not be energised, the apparatus can be authorised under either a dealer licence (L1 / N1) or possession licence (L3 / N2).   

For apparatus that can only be operated by licensed users, the relevant licences or registrations must be obtained. [Note: Only qualified medical professionals and radiographers can be licensed to use irradiating apparatus on living, human subjects.]

Please note that demonstrations, exhibitions and workshops are generally not considered ‘emergency cases’ as they are expected to have been planned in advance. Hence, last minute submission of licence application, resulting in the possibility that licence(s) would not be obtained on time before the demonstration / exhibition / workshop would generally not be considered eligible for expedition of application.


The Health Sciences Authority (HSA) regulates medical devices in Singapore under the Health Products Act (HPA) and its Health Products (Medical Devices) Regulations. HSA evaluates the registration of medical devices based on:

  • Risk classification
  • Number of prior approvals given by their overseas reference regulatory agencies
  • Duration of safe marketing history 

Applicants intending to import, possess for sale or deal in radiation-emitting medical apparatus should check with the Medical Device Branch (MDB) under HSA to ensure that the apparatus is registered and listed on the Singapore Medical Device Register (SMDR), or authorised by HSA, when submitting an application. For more information, please refer to the MDB / HSA website.

NEA officers will contact licence applicants if a pre-licensing inspection is required to evaluate an application. The officer will arrange the date and time of inspection and inform the contact person of any other requirements. A licensee authorised to use the irradiating apparatus or radioactive material and/or a person authorised to represent the applicant organisation should typically be present for the inspection. All NEA officers doing on-site inspection will carry the NEA staff pass and authority card which allows them to exercise the power and the duties as stated in the Radiation Protection Act and its Regulations.

 For L5, L6 and N3 licences and R1 registration:
As the user licences and registrations are tied to the licensee’s identification number, the change in employer will not affect the validity of your user licence or registration. However, L5 / L6 / N3 licensees are to note that the licence must authorise you to use the irradiating apparatus or radioactive materials as required for work under your new employer. You should submit a licence amendment application to update your licence to reflect the irradiating apparatus or radioactive materials that you will be using. 

All other licences: 
Generally, licences tied to UEN cannot be transferred from one organisation to another. When possession of licensed irradiating apparatus or radioactive materials is transferred from one organisation to another, the first organisation should apply for the licence to be cancelled and the new organisation should apply for a new licence under its UEN.
Exceptions may be made for cases where there is a change of UEN arising from amalgamation or mergers or other processes where the former entity is legally recognised as becoming the new entity. Documentary proof (e.g. ACRA documents) must be provided. To check if a licence is eligible for transfer, please contact us at NEA_RPNSD_Licence@nea.gov.sg.  

Medical examination is required when applying for a new user licence or when re-applying for a lapsed user licence. The medical form may be found on NEA ePortal: Miscellaneous Forms.

  • For L5, L6 licences and R1 registration, please bring the medical form (MC-1) to a local medical clinic to arrange for a blood test. The doctor should complete the form.
  • For N3 user licence, please bring the eye examination form (MC-2) to an eye clinic and do the medical eye examination. The ophthalmologist will complete the form before returning it to you.

Please upload the medical examination certificate as a supporting document with your online application. You are advised to keep a copy of the medical examination certificate for your own reference. No other forms of documentation or certification will be accepted in place of the MC-1 or MC-2 unless otherwise informed by NEA.

Please note that: 

  • L6 licences and R1 registration holders engaging in non-destructive test (NDT) radiation work (also known as “industrial radiography”) using Cobalt-60, Iridium-192 or Selenium-75 will need to complete the medical form annually and submit it to NEA when renewing their licences. This annual examination is generally not compulsory for workers who are not in the NDT industry.
  • Licensees with an expired user licence will be required to submit a newly completed medical form when submitting a new application if the medical form was completed more than 12 months ago.

 

Some L5, L6, N3 and R1 applicants may be required to pass the qualifying tests administered by NEA. A notification letter informing applicants of the test date, time, venue, as well as the webpage link to the study materials will be sent to the applicants upon the processing of the submitted licence application. Study materials may also be found at the following website: http://www.nea.gov.sg/our-services/radiation-safety/radiation-protection-services

Note: Study materials provided are only meant as a study guide and not representative of questions that may be tested.

A maximum of 2 test attempts is allowed for the qualifying test, which upon failing both, the licence application will be rejected. There will be no refund of the licence fee for rejected applications.


For existing L5, L6, N3 licensees and R1 registrants that have changed their individual identification number (e.g. changing from FIN to NRIC, etc.), and/or are unable to log in to the GoBusiness Licensing Portal using the SingPass / login ID linked to their former identification number, please contact RPNSD. 


Applicants who would like to learn about radiation safety may do so via the following courses offered by Ngee Ann Polytechnic and Republic Polytechnic. The courses most relevant to the various applicants are as follows:

Type of application

Course and Institution

L5 and L6 licence

Please note that completion of the courses are not mandatory. Applicants for user licences or registration who are required to attend and pass the qualifying test will have a maximum of two attempts at the qualifying test, and failure to pass the test on the second consecutive attempt will result in rejection of the user application. In such cases, we will advise the applicant to attend the radiation safety courses to improve their knowledge in radiation safety. Please also note that completion of the course does not necessarily exempt applicants from having to pass the licence qualifying test administered by NEA.

For more details of the courses, please refer to the respective websites of Ngee Ann Polytechnic and Republic Polytechnic.


Ionising irradiating apparatus
For the decommissioning and disposal of irradiating apparatus, we recommend that the original vendors, manufacturers or any other vendors dealing with similar apparatus be engaged to provide this service as they generally have the necessary expertise to carry out the task safely. The engaged vendor / contractor should provide a formal document indicating that the irradiating apparatus has been decommissioned, disposed, repatriated, exported or transferred before the L3 licence can be cancelled. The serial numbers of the apparatus should be clearly reflected in the document. 

Note: Some parts of the X-ray machine contain toxic materials, such as Beryllium and Lead-glass in the X-ray tube. Such components should be collected by licensed Toxic Industrial Waste collectors for proper disposal. Other components that do not contain toxic materials can be disposed as industrial waste and/or be recycled.

For more information on Toxic Industrial Waste, you may visit the following links:

  1. https://www.nea.gov.sg/our-services/pollution-control/hazardous-waste/toxic-waste-control/

  2. https://www.nea.gov.sg/docs/default-source/our-services/pollution-control/hazardous-waste/list-of-tiw-collectors-(12-may-2021).pdf

 

Radioactive materials (including those as part of an apparatus)
Radioactive materials cannot be disposed of in Singapore except with prior approval from NEA, in writing, authorising the disposal. There is currently no radioactive waste disposal site in Singapore and approval is generally not granted for disposal of radioactive waste (other than waste containing short-lived isotopes that have decayed below control levels). 

Licensees should work with the vendors and manufacturers to repatriate disused radioactive sources or send the sources for recycling or reusing.  


Non-ionising irradiating apparatus
Licensees are advised to approach their apparatus vendor / supplier for the disposal of controlled non-ionising irradiating apparatus. Licensees may also choose to approach any E-waste disposal or recycling companies for such disposals. Disposal certificates / invoices with details of the apparatus (apparatus make, model, serial number, etc.) are to be submitted along with the cancellation application.

A list of E-waste companies can be found on: https://www.nea.gov.sg/our-services/waste-management/3r-programmes-and-resources/collectors-traders-and-local-recycling-facilities


Business entities can authorise a third party in CorpPass to transact on their behalf in the GoBusiness Licensing Portal.

L6A licence applicants must submit a Transport Emergency Response Plan (TERP) covering:

    1. Routes of transportation
    2. Information on radioactive materials to be transported
    3. Product material safety data sheet
    4. Scanned copy of the driver’s Hazardous Materials Transport Driver Permit (HTDP) issued by SCDF
    5. Details of packaging
    6. Photos of vehicles to be used in the transportation
    7. Emergency response procedures

Security requirements
L6A applicants / licensees are required to implement security measures that are in line with guidelines set out by RPNSD. RPNSD may also impose specific requirements on licensees to enhance the security of radioactive materials in transport. 

Individuals intending to be involved in radiation work should be registered as a radiation worker unless he/she is:

  1. a licensee, or
  2. a student carrying out an experiment or researching involving the handling / use of radioactive materials and irradiating apparatus under the direct supervision of a licensee authorised to conduct such experiment or research.

Under the Radiation Protection (Ionising Radiation) Regulations, “radiation work” means work which –

  1. involves the use or handling of any radioactive substance;
  2. involves the use or operation of any irradiating apparatus; or
  3. is required to be carried out in proximity to any irradiating apparatus or radioactive substance or both,

and which is liable to result in the receiving by the individual engaging in it of a radiation dose in excess of one-tenth of the appropriate dose limit for radiation workers as specified in Part I of the Second Schedule. 

IMPORTANT: Please note that licensees should ensure adequate measures are in place to protect all workers from radiation risks. Hence, workers should only carry out work in proximity to any irradiating apparatus or radioactive substance or both, that would make them liable to receive radiation exposure in excess of one-tenth of the dose limit for radiation workers where necessary and justified. R1 applications will be assessed on the justification of the type of radiation work to be carried out by the applicant. Applications found to be unjustified (e.g. reasonable measures can be put in place to avoid radiation exposure; the scope of work does not necessitate radiation exposure) will be rejected.  

The following list shows the common types of radiation work and the specific qualifications and/or conditions for registration. For other types of radiation work, please contact RPNSD for more information.

In particular, class 4 lasers for application on the human body can only be used by registered medical practitioners, at premises approved by the Ministry of Health. Please be reminded that class 4 lasers cannot be used in beauty salons, spas or at home.
  • For laser apparatus used in cutting or marking of materials, take note that some of these materials (e.g. PMMA) may undergo thermal breakdown, releasing hazardous chemical controlled under the legislations administered by various government agencies. Please ensure that the requirements stipulated under these legislations are complied with.
  • Laser marking engraving apparatus shall not be used at home.

Ultrasound apparatus

  • There are special requirements and conditions for the use of medical ultrasound apparatus.
  • Ultrasound apparatus for application on human beings is subject to licensing controlled under the Radiation Protection Act and its Regulations, because of possible misuse and potential adverse health effect.
  • All ultrasound apparatus above 3 W/cm2 must be separately approved by RPNSD before it can be used on the human body. In particular, High Intensity Focused Ultrasound equipment (HIFU) cannot be used in beauty salons, spa or at home. HIFU equipment should only be used by medical practitioners.

MRI

  • There are special requirements and conditions for the use of MRI.
  • Application for the N2 licence for an MRI facility will need to be accompanied by the 5-G line diagram and information on the quenching outlet.


Dealers should note that microwave ovens for local sale will need to comply with provisions listed in the Radiation Protection (Non-Ionising Radiation) Regulations.
