The internship began on Monday, 22nd June, under the supervision of Sohaib Shamim. First, I had to learn the basics of LabVIEW, a graphical programming language that is used extensively in the Physics Lab. We started with a simple LabVIEW tutorial, gaining some familiarity with the key features of LabVIEW, such as the Front Panel, Block diagram, functions toolbox etc. The first exercises requir...
We have repeated our earlier observations of the Infrared and submllllmeter background radiation. While the measured values of the infrared background radiation remain unchanged, we have failed to observe the high flux previously reported for the 0.4 to 1.3 mm range. This indicates that the flux cannot have been galactic or cosmic, but further observations are needed to rule out a solar cycle d...
The paper deals with a specific aspect of a general survey, that is being carried out during last ten years in several regions of Serbia (former Yugoslavia, former Serbia and Montenegro) to assess population exposure to natural radioactivity based on geochemical and integrative pattern research approach. The originality regarding this work is related to the facts such as follows: the first iden...
The city of Ramsar Iran hosts some of the highest natural radiation levels on earth, and over 2000 people are exposed to radiation doses ranging from 1 to 26 rem per year. Curiously, inhabitants of this region seem to have no greater incidence of cancer than those in neighboring areas of normal background radiation levels, and preliminary studies suggest their blood cells experience fewer induc...
n 1987 the International Agency for Research of Cancer (IARC) evaluated radon and its decay products as human carcinogens (1). Large epidemiologic studies conducted in Western Europe in the Õ90s showed that this radioactive gas accounted for 50 to 90% of a radiological dose (2). Very high residential concentrations of radon were measured in Sweden and Finland (3-5). They were 5,000 times higher...
The high level natural radiation areas (HLNRA) of Kerala coast in south west India is unique for its wide variation in the background radiation dose (<1.0mGy to 45mGy/year) and vast population size. Several biological studies conducted in this area did not reveal any adverse effects of chronic low dose and low dose rate radiation on human population. In the present study, global transcriptome a...
All organisms on earth grow under the influence of a natural and relatively constant dose of ionizing radiation referred to as background radiation, and so cells have different mechanisms to prevent the accumulation of damage caused by its different components. However, current knowledge of the deleterious effects of radiation on cells is based on the exposure to acute and high or to chronic, a...
