The activ ity concentrations of naturally occurring radionuclides Ra, Th and K, were measured by using a Broad Energy Ge (BEGe) detector for soil samples collected from the Malnichara tea garden in Sylhet district of Bangladesh. The average activity concentrations of Ra, Th and K in soil samples were found to be 55.284±4.68, 125.270±5.81 and 497.91±43.83 Bqkg, respectively. The results obtained...

background: measurement of background radiation is very important from different points of view especially for human health. the aim of this survey was focused on determining the current background radiation in one of the highest altitude regions ( zagros mountains ), chaharmahal and bakhtiari province, in the south west of iran . materials and methods: the outdoors-environmental monitoring exp...

Background The results of multiple IL-2 clinical trials (using a range of doses) have shown similar trends, in which IL-2 immunotherapy leads to an objective response in 15-20% of patients and complete response in 5-10%. Importantly, the majority (> 80%) of patients with a complete response maintain long-term responses. However, why only a small proportion of patients attain a complete response...

We formulate a stochastic gauge fixing method to study the gauge dependence of Abelian projection. In this method, one can change the gauge from the maximally Abelian one to no gauge fixing continuously. We have found that the linear part of the heavy quark potential from Abelian contribution depends little on the gauge parameter. Similar results have been obtained for the monopole contribution...

“The verifications of Hahnemann convince those who have intellectual integrity for scientific conviction, who will not sacrifice their intellectual integrity to the idols of the day, who will repeat Hahnemann’s experimental verifications of his scientific observations and inductions as they should be repeated. Any other method than to take into the healthy body four drams of China twice a day t...

The shocks and impacts encountered on small high-speed craft exceed the limits set for safe working practice according to current standards. European legislation regarding the exposure to vibration will have far reaching effects on the operators of such craft with respect to the safety of their employees. This paper sets out to highlight the vibration dose values that can be expected during typ...

background: the aim of this study was to investigate clinical applications of mobile c-arms and consequent radiation risk,to increase medical attention on radiation protection, and to provide basic data for safe radiation use in the operating room. materials and methods: in this study, a total of 374 surgical operations, conducted using a portable fluoroscopic x-ray system from january to march...

The paper presents the results of mapping stray radiation fields in three different radiotherapy treatment rooms equipped with three different Co-60 machines. Based on the distribution of the ambient dose equivalent rate, the effective dose to the personnel under various scenarios has been assessed with regard to their movement and position in the room during the preparation of the machine and ...
