Application / Description

The Beta Secondary Standard (BSS) was first developed by the German National Metrology Institute Physikalisch-Technische Bundesanstalt (PTB) nearly 30 years ago for calibrating personal dosimeters and survey instruments for beta radiation. Calibrations are traceable to the PTB’s primary standard, and the BSS meets the requirements of ISO6980.

The new BSS (BSS-2), also developed by PTB, is a complete irradiation facility including beta sources, mechanics, electronics, sensors for air pressure, temperature and humidity, and a personal computer to control all irradiation parameters and to deliver the desired dose to the instrument under test.

The main features of the new facility are:

  • Dosimeters can be positioned easily at the calibrated point in the radiation field
  • Irradiation table rotates in 5 degree steps for measuring polar response
  • High activity Pm-147, Kr-85 and Sr-90 sources with beam flattening filters in place
  • Sr-90 source also calibrated without filter for source-detector distances of 11, 30 and 50cm
  • ·Each source contained in an individual shield with built-in shutter -reduced operator dose, no special handling equipment needed
  • Low activity Tl-204 source replaced by high activity Kr-85 source

For quality assurance purposes and to deliver the required dose to the dosimeter, the computer automatically records the following parameters:

  1. Radionuclide and source identification number
  2. Type of beam flattening filter
  3. Distance between source and dosimeter
  4. Angle of incidence of radiation
  5. Temperature, humidity and air pressure
