What Is Worth Knowing in Interventional Practices about Medical Staff Radiation Exposure Monitoring: A Review of Recent Outcomes of EURADOS Working Group 12

EURADOS (European Radiation Dosimetry Group) Working Group 12 (WG12) SG1 activities are aimed at occupational radiation protection and individual monitoring in X-ray and nuclear medicine practices. In recent years, many studies have been carried out in these fields, especially for interventional radiology and cardiology workplaces (IC/IR). The complexity of the exposure conditions of the medical staff during interventional practices makes the radiation protection and monitoring of the exposed...

Use of Monte Carlo simulations for uncertainty evaluation: A proposed approach for a challenging issue in the dosimetry of high dose per pulse electron beams using plane-parallel chambers

This paper describes a Monte Carlo (MC) approach to assess the ion recombination correction, ks and its associated uncertainty, u(ks), in plane-parallel chambers used in high dose-per-pulse electron beam dosimetry. The proposed method was applied to assess ks and u(ks) as a function of the ratio Q1/Q2, i.e., the charge collected at polarizing voltages V1 and V2, in a plane-parallel chamber with electrode spacing ℓ = 2 mm. Data were fitted to a general quadratic function with the aim to derive...

Mechanical impact of electromagnetic transients on the European DEMO divertor. Part 1: Vertical displacement event

This paper presents the study of the forces and moments expected on the European DEMO divertor, due to the fast electromagnetic transients associated to plasma instabilities events. A 3D Magneto-Quasi-Static (MQS) model is here adopted to solve such a problem, implemented in Ansys EMAG. A hybrid modelling approach is proposed, that can be placed between a pure global model (where the divertor is modelled along with all the external passive and active components) and a local one, where only th...
