Spherical Chamber TK-30
Spherical ionization chamber with a long rigid stem for radiation protection measurement
- Vented sensitive volume of 28 cm³
- Suitable as high precision reference chamber for radiation protection dosimetry
- Very flat energy response within a wide range
The spherical graphite chamber TK-30 has been designed as a reference chamber for absolute dosimetry to be used by secondary standard dosimetry laboratories (SSDL) and users with high quality requirements.
It has very small variations of response with radiation quality from low X-ray energies up to high-energy photon radiation.
The guard ring is designed up to the sensitive volume. The chamber is constructed with a long rigid stem of approx. 20 cm length for easy mounting in the radiation beam. Air density correction is required for each measurement.
