The purpose of this Medical Physics Practice Guideline (MPPG) is to describe the minimum level of medical physics support deemed prudent for the practice of linear-accelerator, photon-based (linac) stereotactic radiosurgery (SRS), and stereotactic body radiation therapy (SBRT) services. This report is an update of MPPG 9.a published in 2017. As SRS and SBRT services are rapidly adopted into the community-practice setting, this guideline has been developed to build on the work presented in MPPG 9.a and provide current appropriate minimum practice guidelines for such services.

Objectives: Establishing paediatric DRLs is challenging due to sparse data availability. The objective was to assess paediatric fluoroscopic dose levels in Dutch clinical practice, as current diagnostic reference levels (DRLs) need updating following the European Guidelines on DRLs for Paediatric Imaging (PiDRL).
Material And Methods: Air Kerma-area Product (KAP) values were retrospectively collected from paediatric patients (0-18 years) who underwent fluoroscopic procedures in nine Dutch hospitals between 01-01-2017 and 01-06-2021.

This study compares the dosimetric performance of Base Dose Optimization (BDO) and Gradient-Based Optimization (GBO) for extended target volumes in Total Body Irradiation (TBI). The focus is on overlapping regions using the Rando Phantom. The study evaluates dose distribution, conformity, homogeneity, and sensitivity to positional deviations.

Industrial emissions of cadmium, which is used in various industries, and formation of cadmium nanoparticles during high-temperature technological processes aggravate the problem of chemical pollution. Insufficient understanding of the toxic impact of cadmium nanoparticles, coupled with the serious multisystem toxicity of this metal, necessitate expansion of knowledge about their potential toxic effects. We assessed the response of female outbred albino rats to subchronic exposure to cadmium oxide nanoparticles (CdO NPs) administered intranasally at the concentration of 0.
