background: the rejected films in radiography may be responsible for an unnecessary increase in the radiation dose to the population. the effective dose to population is a very important factor in estimation of stochastic risk in radiology. the main goal of this study was to determine the effective dose to members of the public due to rejected films in diagnostic radiology departments in the no...

An attempt has been made in the work to assess radiological dose due to the deposition of 131 I, 132 I, 133 I, 134 I, and 135 I on ground, vegetation, milk and meat considering a hypothetical accident of TRIGA Mark-II research reactor at AERE, Savar, Bangladesh. Contribution of dose from ingestion of vegetation due to 131 I has been found to be dominant (62.96%). Also found that contribution of...

One primary purpose in a dose–response study for drug development is to identify the minimum effective dose (MED), which is the lowest dose level producing an effect over that of the zero-dose control. Proposed herein is a nonparametric step-down closed testing procedure for identifying the MED in a randomized block design with one or more observations per cell. The associated p-value of the id...

The initial microstructure and mechanical properties of composite powders have a vital role in determining the microstructure and mechanical properties of the subsequent consolidated bulk composites. In this work, Al-based matrix composite powders with a dense and uniform distribution of metallic glass nanoparticles were obtained by high-energy milling. The results show that high-energy milling...

Pathogen aggressiveness on the host was studied as one of the influencing factors in the variability of the efficiency of biocontrol by Pantoea agglomerans. The effect of the relative dose of the pathogen and biocontrol agent (BCA) on efficacy of biocontrol was analyzed in six postharvest pathogens (Rhizopus stolonifer, Botrytis cinerea, Penicillium expansum, Monilinia laxa, Penicillium digitat...

The radionuclide contents and their activity concentrations in beach sand, sediment and adjacent soil samples collected from Inani sea beach, Cox’s Bazar, Bangladesh were determined by using a high resolution germanium detector (HPGe) of 20% relative efficiency. A total of eighteen samples of three categories were collected and analysed. The activity concentrations of Ra, Th and K in the sand s...
