• Equipment used: ionization chamber connected to the main standard of CMI. State standard of exposure, exposure power, kerma in air and kerma rate in air of photon radiation | Czech Metrological Institute (cmi.cz)
• Calibration method: Comparative measurement with an external radionuclide source. The radionuclides used may vary according to the availability of an external radionuclide source (e.g. Co-60, Cs-137, Ir-192, Se 75)
• Quantities of ionizing radiation dosimetry and their range:
Quantities of ionizing radiation dosimetry | Range |
---|---|
Kerma in air Ka | 15 Gy – 25000 | Gy
Kerma rate in air pKa | 15 Gy/h – 25000 Gy/h |
