Accurate measurement of low-level thoron gas and high-accuracy calibration devices are essential for assessing preventing radiological risks. This study aimed to develop a technique using an airflow-through scintillation cell both calibration. To achieve this, compartment model was developed estimate the influence progeny deposition accumulation on wall prevent overestimation thoron. A self-dev...

Background: Irreversible electroporation (IRE) is a novel tumor ablation technique. IRE is associated with high electrical fields and is often reported in conjunction with thermal damage caused by Joule heating. For good response to surgery it is crucial to produce minimum thermal damage in both tumoral and healthy tissues named Non-Thermal Irreversible Electroporation(NTIRE). Non-thermal irrev...

the present study attempts to investigate the effect of thermal treatment at 180 °c for 8 hours on chemical changes, quality indexes and oxidative stability of three iranian common virgin olive oils (zard, mari and phishomi). oil samples were taken every 2h of heating treatment and assessed for fatty acid composition, conjugated diene value, carbonyl value, color index and oxidative stability i...

Abnormal increases in radon ((222)Rn, half-life = 3.82 days) activity have occasionally been observed in underground environments before major earthquakes. However, (222)Rn alone could not be used to forecast earthquakes since it can also be increased due to diffusive inputs over its lifetime. Here, we show that a very short-lived isotope, thoron ((220)Rn, half-life = 55.6 s; mean life = 80 s),...

Telah dilakukan pengukuran konsentrasi gas radon (Rn-222) dan thoron (Rn-220) menggunakan detektor CR-39 pada ruangan kelas di Kota Lubuk Basung. Penelitian bertujuan untuk menentukan data awal dalam ruangan, kemudian ditinjau berdasarkan ICRP Publikasi No. 126 tahun 2014. Pengukuran sebanyak 50 buah yang dipasang selama 3 bulan 9 lokasi sekolah. Detektor selanjutnya dietsa larutan NaOH 6,25N 7...
