National Dose Register

According to the International Atomic Energy Agency’s (IAEA) Safety Standards, the regulatory body must make provision for establishing and maintaining records of occupational radiation doses. The regulatory body may or may not be the sole entity responsible for the maintenance of these registers and inventories, and it may be involved in the proper retention and use of such records. International best practice for record keeping of internal and external national occupational radiation doses requires the utilisation of a central dose registry. To this end, the Joint Coordination Committee, formed by the regulatory bodies in South Africa, mandated a working group to establish a National Dose Register (NDR). The NDR is a centralised system for recording occupational radiation exposures in the country. The NDR data can be used for tracking a registered worker’s cumulative dose based on data provided by the authorisation holder or dosimetry service provider. The Joint Coordination Committee approved a proposal to use the IAEA Regulatory Authority Information System (RAIS) software application as a basis for the development of the NDR. The proposal, which was included in an IAEA technical cooperation national project, referred to international practice, available software and databases, a proposed location and the eventual establishment of a National Dose Register.

Uploading Records

Upload Template 

An Excel template was developed for the upload of records to the NDR. The template was tested, reviewed and updated in line with improvements identified during the pilot studies.

The template includes the following fields:

  • Regulatory authority number;
  • Company identification details;
  • Worker identification particulars ;
  • Worker status and activities;
  • Effective doses and time periods;
  • Additional dose information; and
  • Reference list (country name, practice code).

Data Upload Mechanism

During the testing phase all data providers were assigned a master account responsible for the creation of subaccounts and uploading records. Nuclear authorisation holders were granted access to upload all their records while dosimetry service providers will upload all records from medical, industrial and scientific authorisation holders.

The upload frequency of records is performed in line with authorisation conditions and data providers are responsible for the confidentiality and accuracy of records. Worker consent is captured in the NDR and controlled through the data providers’ internal policies. Auditable access trails are also built into the system.
