The TRMM rainfall product 3B42 is compared with rain gauge observations for Kaiga, India on monthly and seasonal time scales. This comparison is carried out for the years 2004-2007 spanning four monsoon seasons. A good correlation is obtained between the two data sets however; magnitude wise, the cumulative precipitation of the satellite product on monthly(More)
Assessment of intake due to long-lived actinides by inhalation pathway is carried out by lung monitoring of the radiation workers inside totally shielded steel room using sensitive detection systems such as Phoswich and an array of HPGe detectors. In this paper, uncertainties in the lung activity estimation due to positional errors, chest wall thickness(More)
The estimation of Pu/(241)Am ratio in the biological samples is an important input for the assessment of internal dose received by the workers. The radiochemical separation of Pu isotopes and (241)Am in a sample followed by alpha spectrometry is a widely used technique for the determination of Pu/(241)Am ratio. However, this method is time consuming and(More)
In the title compound, C12H11N3O3·2H2O, the dihedral angle formed by the planes of the pyridine and the furan rings of the organic carbohydrazide mol-ecule is 4.66 (7)°. In the crystal, these mol-ecules form stacks along the b-axis direction, neighbouring mol-ecules within each stack being related by inversion and the shortest distance between the centroids(More)
The title compound, C14H13N3O3·H2O, adopts an E conformation with respect to the azomethine bond and crystallizes in the amide form. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, the lattice water molecule plays a major role in the supramolecular architecture by interconnecting adjacent molecules into a three-dimensional netwrok by means of(More)
The measurement of tritium in environmental samples requires highest possible sensitivity. In the present study, the authors have optimised the counting window for the analysis of (3)H in environmental samples using the recently installed Ultra Low Level Quantulus 1220 Liquid Scintillation Counting at BARC to improve the detection limit of the system. The(More)
An extensive study has been carried out within the site of Bhabha Atomic Research Centre, Trombay, for examining the atmospheric dispersion of (41)Ar released from research reactors. The release rate, release height, meteorological parameters and geographical information were used to establish correlation between theoretical estimation using Gaussian plume(More)
In case of internal contamination due to long-lived actinides by inhalation or injection pathway, a major portion of activity will be deposited in the skeleton and liver over a period of time. In this study, calibration factors (CFs) of Phoswich and an array of HPGe detectors are estimated using skull and knee voxel phantoms. These phantoms are generated(More)
Business Escalation Management framework was conceptualized as a governance and issue resolution channel for complex business relationship scenarios demanding immediate attention from the management. Escalation in a business engagement scenario is often a deterrent to the overall health of the relationship. In organizational business units, there are(More)
Various parameters can introduce uncertainties in the lung activity measurements of actinides. In this study, uncertainties due to non-uniform distribution of activity in the lungs are evaluated. To study the effect of non-uniform distribution, lungs of ICRP male thorax voxel and resized phantoms are divided into upper and lower parts of both right and left(More)
