Ionizing Radiation

Division 6

Almost everything dealt with at Division 6 centres on the nucleus, for here radioactivity, dosimetry and metrology of alpha, beta, gamma, X and neutron radiation are concerned - from radiation therapy in medicine to the measurement of radioactivity in the environment.

Tasks

The Division is concerned with the metrology of ionizing radiation. Important tasks cover measuring techniques for the detection of ionizing radiation, dosimetry for radiotherapy, radiodiagnostics and radiation protection, radiation measurements in the environment, activity measurements and the determination of atomic and nuclear data. The units of activity, fluence rate, air kerma, absorbed dose and dose equivalent are realized and disseminated via calibrations. The Division thus ensures the uniformity of measurements in the field of ionizing radiation.

Legal tasks are based on the Units and Time Act, the Verification Act, the Medical Products Act, the Radiology and the Radiation Protection Ordinance and the Radiation Protection Preventive Act. Activity standards for about 50 radionuclides are produced and made available. The Division performs type testing of X-ray equipment, X-ray tube assemblies, parasitic X-ray emitters, area and personal dosemeters, and dosemeters for radiodiagnostics. In addition, the Division deals with fundamental research work in the fields of radioactivity, dosimetry and metrology of alpha, beta, gamma, X-ray and neutron radiation.

News

Im Rahmen des EMPIR-Projekts RemoteALPHA „Remote and real-time optical detection of alpha‑emitting radionuclides in the environment“, das am 1. September 2020 startete und von der PTB koordiniert wird, wird ein neues Erfassungssystem und eine neue metrologische Infrastruktur für die optische Detektion von Alphastrahlern in der Umwelt durch Ausnutzung der Radiolumineszenz entwickelt. Dies wird eine...
