Spherical Graphite Chambers PS- 50 and PS-10 (32007S and 32008S)
Primary standard spherical ionization chambers for radiation protection measurement
- Vented sensitive volume of 50 cm³ and 10 cm³
- Suitable as primary standard for radiation protection measurements
- Individual determination of exact volume
- Designed in collaboration with NIST (National Institute of Standards and Technology)
The spherical graphite chambers PS-50 and PS-10 are vented ionizing chambers for use as primary standard for radiation protection measurements and absolute dosimetry. They have been designed in collaboration with the Radiation Interactions and Dosimetry Group at the National Institute of Standards and Technology (NIST).
The exact volume of each chamber is determined individually. The homogeneity of the walls and electrodes is 0.06 mm.
The chambers are constructed with a long rigid stem of approx. 29 cm length for easy mounting in the radiation beam. Air density correction is required for each measurement.
