What is PD IEC TR 61948‑4 - Routine tests for radionuclide calibrators about?
PD IEC TR 61948‑4 is a standard on the routine tests for nuclear medicine instrumentation that outlines radionuclide calibrators to ensure stable operability, safety and performance in medical applications.
PD IEC TR 61948‑4 is the fourth part of a multi-part series that covers the routine testing of radionuclide calibrators used in nuclear medicine. Such devices utilise ionisation chambers of the good type and a direct readout in units of activity. Requirements and specific methods to determine performance parameters are described in IEC 61303. The methods under PD IEC TR 61948‑4 are primarily designed for acceptance testing.
Who is PD IEC TR 61948‑4 - Routine tests for radionuclide calibrators for?
PD IEC TR 61948‑4 on the routine tests for radionuclide calibrators is relevant to:
- Medical laboratory and testing houses
- Radionuclide calibrators manufacturers
- Personnel conducting routine tests for radionuclide calibrators
Why should you use PD IEC TR 61948‑4 - Routine tests for radionuclide calibrators?
Ionization chambers and electrometers are used in radionuclide calibrators. The ionisation chamber is a type of gas-filled detector. Between two electrodes with a voltage difference (and consequently an electric field) between them is a volume of gas. They are used to measure the radiopharmaceutical activity, that is to be administered to patients.
PD IEC TR 61948‑4 assists you with the test methods, including background response, constancy of instrument response, system linearity, additional check and frequency of routine tests, to ensure the development of an efficient framework and safety protocols for radionuclide calibrators.
With obedience and compliance of PD IEC TR 61948‑4, you can assess radionuclide calibrators for detection and prevention of faulty equipment to ensure their applicability in medical applications.
What’s changed since the last update?
