Main text The introduction over the last decade of radionuclide therapy based on 223 Ra and 227 Th has reawakened interest in radionuclides 235 U decay series (the 4n+3 chain). This coincided with a requirement for improved accuracy dating long-lived nuclear forensic geological purposes. Thus, 231 Pa become subject revived recent years. short-term ingrowth progeny is to science since it enables direct calculation separation age enriched [1] ; times 234 U- 230 chain may also be calculated,...

Radioluminescence mapping using well-characterized and optimized optical systems is an effective method for localizing contamination with alpha-emitting radionuclides. To apply this novel approach to radiological emergency management, nuclear safeguards, decommissioning, forensics, established traceability chain required. This work presents the development implementation of a calibration methodology provide valuable information about, confidence in, performance radioluminescence detection...

According to a first program, supplementary comparison of Rn-222 volume activity was drawn up as bilateral between NSC 'Institute Metrology', Ukraine, and VNIIFTRI, Russia. It took place in March 2005.
Prior to 2002, no comparisons of radon activity concentration had been performed within the scope EUROMET. The comparison presented here fulfils need provide confidence in capability national metrology institutes and calibration laboratories measure air. This has achieved by measurement reference atmospheres using an electronic, measuring instrument as transfer device (CD). Each twelve institutes, from nine countries, calibrated CD standard procedures according their quality system, at three...
Abstract. More than 50 % of naturally occurring radiation exposure to the general public is due noble gas radon (222Rn) and its progenies, causing considerable health risks. Therefore, European Union has implemented Council Directive 2013/59/EURATOM measure 222Rn activity concentrations identify priority areas (RPAs) specify where countermeasures are most needed. Although measurements far spread across Europe, traceability International System Units (SI) still lacking for below 300 Bq m−3....
Main text An international comparison of activity per unit volume 222 Rn (EURAMET project N° 1475, registered in KCDB as supplementary EURAMET.RI(II)-S8.Rn-222) was organised 2019 within the framework European MetroRADON. The LNE-LNHB is pilot comparison. Samples gas provided by were sent to participants and measured using various techniques. reference value power moderated mean (PMM) (Pommé, 2013) seven submitted results.
