important experiments on total and regional lung deposition for healthy subjects has recently been published by the International Commission on Radiation Protection (ICRP) [2]. The mean values of experimental deposition data are approximated by mathematical expressions, which are then implemented into a computer program [3] that is commercially available on diskette. Since this model is applica...

Abstract The possibility using Raman spectroscopy in the analysis of samples for urease breath test to diagnose presence bacterium Helicobacter pylori has been demonstrated. scattering spectra air exhaled by a person were obtained, volume fractions 12 CO 2 and 13 exhalation determined.

Natural radioactivity has been determined by means of a highly efficient thallium-doped sodium iodide detector in soil sample from surface vicinage “Kolaghat Thermal Power Plant” The activity concentration (specific activity) is found to vary 23.70 ± 3.41 33.90 4.33 Bqkg-1 for 226Ra, 6.67 2.01 21.60 2.11 232Th and that 40K 461.01 66.16 610.25 80.87 with expected value 29.26 3.50, 4.86 2.03 517....

The measurement of (86)Rb turnover recently has been suggested as a useful method for measuring field metabolic rate in small animals. We investigated a proposed mechanism of (86)Rb turnover, its analogy to K(+), by comparing the turnover of (86)Rb in a model insect, the rhinoceros beetle Xylotrupes gideon, fed a diet of plum jam or plum jam enriched with K(+) or Rb(+). The turnover of (86)Rb i...

Repeatability studies are gaining considerable interest among physiological ecologists, particularly in traits affected by high environmental/residual variance, such as whole-animal metabolic rate (MR). The original definition of repeatability, known as the intraclass correlation coefficient, is computed from the components of variance obtained in a one-way ANOVA on several individuals from whi...

The present study involves the measurement of radionuclide contents and radon/thoron exhalation rate in soil samples collected from 30 villages Jammu district, J & K, India. Thallium-doped sodium iodide detector advanced Smart Rn Duo monitor were used for rates. radon flux was also measured by using a surface chamber technique. mass has been found to vary 15 ± 0.4 38 0.8 mBq kg?1 h?1, while tho...
