Dosimetrisch

Dosimetrisch is an adjective used in Dutch- and German-speaking contexts to denote matters related to dosimetry, the science and practice of measuring and calculating radiation dose. Dosimetry is essential in medicine, industry, and research wherever ionizing radiation is used.

Dosimetry encompasses physical measurements of dose in materials and biological tissue, as well as computational methods for predicting dose distributions. It includes absorbed dose, dose rate, and dose distribution, often represented as a map showing how dose is delivered across a volume.

Common units are gray (Gy) for absorbed dose and sievert (Sv) for dose equivalents and effective dose, which account for biological effect. Dose calculations may be performed per treatment plan, per diagnostic exam, or for occupational exposure.

Applications include radiotherapy treatment planning and verification, diagnostic radiology, nuclear medicine, and occupational or environmental dosimetry. Dosimetric accuracy directly influences treatment outcomes, image quality, and safety.

Methods combine physical measurement with computational modelling. Detectors such as ionization chambers, thermoluminescent detectors, and optically stimulated luminescence dosimeters are used for calibration and in-phantom measurements, while Monte Carlo simulations and treatment planning systems compute dose distributions. Quality assurance and standardisation by bodies such as ICRU, IAEA, and IEC ensure traceability and uncertainty control.

In English-language contexts the adjective dosimetric is common; dosimetrisch is the cognate form in Dutch and German.
