Manganese clay is a residue of manganese ore processing and is generated in huge amounts. This residue may contain some radionuclides with elevated concentrations. In this study, the radon emanation features and the massic exhalation rate of the heat-treated manganese clay were determined with regard to brick production. From the manganese mud depository, 20 samples were collected and after homogenization radon exhalation characteristics were determined as a function of firing temperatures from 100 to 750 °C. The major naturally occurring radionuclides 40K, 226Ra and 232Th concentrations were 607 ± 34, 52 ± 6 and 40 ± 5 Bq kg−1, respectively, comparable with normal clay samples. Similar to our previous studies a strong correlation was found between the internal structure and the radon emanation. The radon emanation coefficient decreased by ∼96% from 0.23 at 100 °C to 0.01 at 750 °C. The massic radon exhalation rate of samples fired at 750 °C reduced by 3% compared to samples fired at 100 °C. In light of the results, reusing of manganese clay as a brick additive is possible without any constraints. © 2016 Elsevier Ltd LA - English DB - MTMT ER - TY - JOUR AU - Shahrokhi, Amin AU - Vigh, Tamás AU - Németh, Csaba AU - Csordás, Anita AU - Kovács, Tibor TI - Radon measurements and dose estimate of workers in a manganese ore mine JF - APPLIED RADIATION AND ISOTOPES J2 - APPL RADIAT ISOTOPES VL - 124 PY - 2017 SP - 32 EP - 37 PG - 6 SN - 0969-8043 DO - 10.1016/j.apradiso.2017.02.047 UR - https://m2.mtmt.hu/api/publication/3219132 ID - 3219132 N1 - Institute of Radiochemistry and Radioecology, University of Pannonia, 10 Egyetem str, Veszprém, H-8200, Hungary Manganese Mine Ltd.

Box 158, Hungary; email: kt@almos.uni-pannon.hu AB - In the new European Basic Safety Standard (EU-BSS), a new reference level for indoor radon concentration in workplaces has recommended that the annual average activity concentration of indoor radon shall not be higher than 300 Bq m−3. This paper describes the radon concentration level in an underground workplace (manganese ore mine) over long time intervals (4 years). Several common radon monitors devices – including NRPB and Raduet (as a passive method based on CR-39), AlphaGUARD PQ 2000Pro, SARAD EQF3220, TESLA and Pylon WLX (as active methods) – were used for continuous radon measurements. The output results were used, first, to comprised the result of each device, based on conditions present in underground mines; Second, to have comprehensive measurements about all factors that cause workers exposure to radiation (each monitoring device specified for a unique measurement). The results indicate that the mine's staff had successful efforts to reach the strict requirement of the new EU-BSS, and the average annual radon activity concentrations during the working hours were below 300 Bq m−3 in the investigated period. The paper presents the effective dose calculations; applying different equilibrium factors suggested by the literature and calculated basing on our measurements at the site, concluding that the differences could be about threefold. © 2017 Elsevier Ltd LA - English DB - MTMT ER -
