Ionising Radiation Approvals

All use of ionising radiation needs to be authorised under the OHS Prescribed Activities approvals system. If you are purchasing an ionising radiation source (X-ray, sealed source, unsealed radioactive material) you will need a Prescribed Activities Approval for that activity. If you are using a source already in place, you will need to confirm with your supervisor/lab manager/RSO whether your work will be covered under an existing Approval, or if you need to obtain a new Approval.

Approvals are checked against Monash’s Radiation Management Licence by the University Radiation Protection Officer, and by the local RSO for suitability of facilities and appropriate risk management.

Approval Application form

Note that if you are applying for an approval for an X-ray, sealed source, or sealed source apparatus, you will need to know the DHHS reference number. If you do not have a DHHS reference number, register the apparatus using the Radiation Asset Management Form before applying for approval. If you do not have the necessary information to do this, contact the RPO margaret.rendell@monash.edu

Some guidance for form fields;

Does this OHS Approval need to be extended to other person(s)?

For unsealed radioactive material, each person purchasing an isotope must be listed on a relevant Approval. An area or research group may choose to consolidate all purchasers of a given isotope on a single Approval, or apply for them individually.

The Approval for an apparatus/sealed source should be held by the person with management control over that source (often the RSO), and other persons may use the source at that person’s discretion without their own Approval.

Date/Time Approval required

Time is not relevant for radiation approvals

Date/Time Approval end

Approvals will not usually extend beyond the extent of Monash’s current DHHS Radiation licence (03/07/2023), but can be shorter if only needed for a limited time.

Monash Space

Select the required Building/Floor/Room and “Add”. After a short delay, the location will appear under “Selected Locations”.

If an isotope or mobile source is to be used in more than one laboratory, a second (third, etc) location can be entered after the first.

Do you know the Department of Health reference number?

Radioactive material does not need a reference number. For equipment/sealed sources, if you do not have a DHHS reference number, then you should register the apparatus using the Radiation Asset Management Form before applying for approval.
