Fernandesa Biología OSL humidity dosimetry hygroscopy Several materials are being studied for dosimetric applications; some of them have the hygroscopic property that is not suitable for dosimetry. In this research, a new low-cost option for performing OSL measurements is presented. A transparent enamel was tested for sticking the powdered samples on an aluminum disc. Also, to avoid the absorption of humidity, the samples were covered with enamel. Although the signal decreases with waterproofing, the reproducibility and fading will no longer depend on their hygroscopic properties. Therefore, the aliquots with enamel may be submitted to irradiation and OSL reading with pre-heating up to 160 °C safely. Finally, by carrying out the irradiation and reading process, more than 100 times with an assisted temperature of 120 °C, the reproducibility was verified. 2022 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280973014 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.10 |
