  1. Placement – place dosimeter in position before irradiation. 

  2. Irradiation – irradiate dosimeter at a known location and time. 

  3. Retrieval – retrieve dosimeter from placement position. The time interval between irradiation and heat treatment should be considered as an influence quantity.

  4. Post-Irradiation Heat Treatmentheat treatment of B3 dosimeters after irradiation is required for most applications to stabilize the response

  5. Measurement – measure the dosimeter per an established method. 

  6. Retention – for a period that best suits the needs of the application requirements. For example, the need to re-check measurements. 

  7. Dispose - Dispose of dosimeter in a general waster receptacle based on user requirements.
