- Development and calibration of a portable detection device for in vivo measurement of high-energy photon emitters incorporated by humans Alexandre Barbosa Soares Mayara Nascimento Arbach Éder Augusto de Lucena Ana Letícia Almeida Dantas Bernardo Maranhão Dantas Biología Bioassay Internal dosimetry Internal monitoring This work presents the evaluation of the applicability and sensitivity of a portable detection device specially designed for in vivo measurement of high-energy photon emitters in the human body. The calibration was performed at the In-Vivo Monitoring Laboratory of the IRD. The equipment consists of a lead-collimated NaI(Tl) 3”x3” scintillation detector assembled on a tripod. The detector and its compact associated electronics are connected via USB cable to a portable PC. Spectrum acquisition and analysis is controlled by specific commercially available software. The calibration was performed using a standard liquid source of 152Eu contained in 3 L polyethylene bottles. The evaluation of the system is based on the estimation of the minimum committed effective doses associated to the minimum detectable activities, calculated using current biokinetic and dosimetric models available in the literature. The dose detection limits for selected radionuclides of interest in an emergency scenario have shown to be far below 1 mSv allowing the system to be useful in accident situations. 2018 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280826004 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.2A Vol.6
