“…Annual production of narrow‐clawed crayfish was 1233 tonnes in 2020, 85% of which (1051 tonnes) was from sampling areas (Turkstat, 2022). Eğirdir Lake is Turkey's second‐largest freshwater resource (457 km 2 surface area), and is 918 m above sea level with an average depth of 9 m (Özseven et al, 2020). Hirfanlı Dam, built in 1959 on the Kızılırmak River, has a 218.81 km 2 average surface area and 20.15 m average depth (Gençoğlu & Ekmekçi, 2016).…”

We quantified bycatch rates and determined selection criteria of landed narrow‐clawed crayfish (Pontastacus leptodactylus) in Turkey's most crucial crayfish production centres in 2020 and 2021. Subsamples (6078 individuals) of catches from 225 commercial fishermen were compared to 4836 crayfish landed without selection criteria during research fishing. Selection criteria used by traders for crayfish in commercial fishing purchasing centres included: (i) undersized; (ii) dead; (iii) soft shells; (iv) missing extremities; (v) lesions; and (vi) covered with moss. Based on the selection criteria, 77.2% ± 4.1 (95% confidence interval: 68.4–86.0) of the commercial catch were removed from the production chain as landed bycatch. The bycatch rate was higher than the global marine bycatch rate (40.4%). New studies are needed to improve fyke net selectivity, reduce the bycatch rate (40.7%) of undersized individuals, and determine the fate of bycatch.

“…The comprehensive absorbed dose rate in the atmosphere can be calculated concerning the concentrations of terrestrial nuclei. The collective airborne absorbed dose rate, denoted as D (nGy/h), over the terrestrial landscape resulting from the presence of 226 Ra, 232 Th, and 40 K within the soil samples at each site, is determined using the subsequent equation [5,16,17] :…”

This study aimed to minimize radiation risk in Solok Selatan by analyzing active concentrations of 226Ra, 232Th, and 40K, calculating excess lifetime cancer risk (ELCR) from annual effective dose equivalent (AEDE). Soil samples from seven sites in the Solok Selatan, 0 – 5 cm deep, were tested with a high-purity germanium (HPGe) detector. 232Th concentrations exceeded the established global standard of 30 Bq/kg. In addition, the study included the determination of Radium Equivalent (Raeq), absorbed gamma dose rate (D), AEDE, and ELCR. Annual effective dose ranged from 68.33 to 19.92 μSv/y, below the global average of 80 μSv/y. The ELCR, the critical measure for understanding potential health risks, was 0.27 ± 0.12 x 10-3, under the global average of 0.29 x 10-3. Interestingly, areas closer to the geothermal sources, especially Koto Baru and Sungai Pagu, showed slightly higher natural radioactivity and corresponding effects. These findings emphasize the importance of rigorous surveillance and proactive measures in areas with high radioactivity characteristics. In summary, the results of this study provide important insights into the radiological landscape of Solok Selatan, urgently assisting in addressing potential health risks through informed risk assessment and strategies.

X‐ray shielding parameters of lanthanum oxide added waste soda‐lime glass

et al. 2020

Besides various materials, glass becomes very important, as it has started to be used in many applications. Thus, their radiation shielding properties should be determined for safely using in critical applications such as for medical purposes With this in mind, the present study investigated the radiation shielding parameters of waste soda‐lime (SLS) containing varying amounts of lanthanum oxide (La2O3). The La2O3 content was added as 0.005, 0.05 and 0.5 in wt% into waste SLS glass, and four different glass specimens (La‐0, La‐0.005, La‐0.05, and La‐0.5) were produced via conventional melting technique. The linear attenuation coefficient for glass samples was measured in the photon energies of 511,835 and 1,275 keV and the results were compared with the calculation done by XCOM. One can conclude that adding lanthanum oxide to waste glass is an effective way to improve radiation shielding properties of glass. That is, the sample of La‐0.5 could provide a higher linear attenuation coefficient while lower half‐value thicknesses. Further, the findings obtained both in calculation and experimental showed a good agreement for all types of glass and also for all energies.
