Aims :

• To consider dosemeters and dosimetry requirements.
• To consider airborne activity and air samplers.

Objectives :
By the end of this course the student will be able to:

• State what radiations are measured by the following dosemeters: film, electronic, fast neutron, criticality locket and extremity TLDs.
• State which dosemeters are approved for whole body and extremity measurements.
• State the requirements of NRSI 3, 13 and 14.
• Explain the requirements for the control of doses to contractors and the difference between a 'legal' and 'non-legal' dosemeter.
• Define the annual limit on intake and the derived air concentration and explain the relationship between these terms.
• Explain how the DAC for a single radionuclide is determined.
• Explain how airborne activity is measured using particulate air samplers, radioactive gas monitors and bubblers.
