The measurements of Ra, Th and K using gamma spectrometry and radon concentration and exhalation rates measurements using solid state nuclear track (LR-115, Type-II plastic) detectors are used to asses a first order exposure risk for the persons residing in Fatehbad and Hissar districts of Western Haryana, India. The concentration of Radium, Thorium and Potassium in the soil samples varies from...

OBJECTIVE Our goal was to observe the duration of inhaling and exhaling as well as the inhalation to exhalation conversion in patients with lung cancer and experimental dogs. MATERIALS AND METHODS We recorded lung and tumor respiratory motion with X-ray camera, in five patients with lung cancer as well as in five experimental dogs. We made random observation of breathing cycle inhalation dura...

BACKGROUND Expiratory flow rate, soft palate closure, and dead space air may influence exhaled levels of nitric oxide (NO). These factors have not been evaluated in the reservoir collection of NO. METHODS Exhaled NO was collected into a reservoir during a single flow and pressure controlled exhalation. RESULTS NO collected in a reservoir containing silica gel was stable for 24 hours. Nasall...

This study aims to assess the environmental hazards from radon exhalation rate in the soil samples in selected locations in Iraqi Kurdistan, using passive (CR-39NTDs) and active (RAD7) detecting method. Radon concentration, effective radium content and radon exhalation rate were estimated in soil samples that collected at the depth level of 30 cm inside 124 houses. The results show that the ema...

Five locations and five samples of materials from the phosphogypsum waste stack near Zgrpolci locality, in vicinity city Veles, were checked for their radon concentrations air exhalation rate. The accumulation method using AlphaGUARD DF2000 device was used specific rate determinations as well air. activity 222Rn at 5 different sampling anthropogenically introduced phosphogypsym locality ranged ...
