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...

background: the induction of cancer appears to be the most important effect of low-dose ionizing radiation to occur in an exposed population. in developing countries 94% of human radiation is from natural sources. in iran some high altitude regions such as, chaharmahal & bakhtiari has high levels of the natural background radiation (higher than the worldwide average). therefore, investigation o...

Telomere length and stability is a biomarker of aging, stress, and cancer. Shortening of telomeres and high level of DNA damages are known to be associated with aging. Telomere shortening normally occurs during cell division in most cells and when telomeres reach a critically short length, DNA damage signaling and cellular senescence can be triggered. The induction of an adaptive response by sp...

Background: The natural radionuclides are always present in soil and care needs to be taken to minimize the radiation dose to humans. These radionuclides are mostly gamma ray emitting radionuclides which contribute to the radiation dose in long term behavior of radionuclides in soil. Health hazards associated with natural radioactivity are of great concern and it is necessary to assess risk due...

Ionizing radiation has been shown to produce negative effects on organisms, although little is known about its ecological and evolutionary effects. As a study model, we isolated bacteria associated with feathers from barn swallows Hirundo rustica from three study areas around Chernobyl differing in background ionizing radiation levels and one control study site in Denmark. Each bacterial commun...
