India has more than 300 thermal springs spread over the entire geographical area of the sub-continent Some of these springs have linkage with Indian mythology and are famous pilgrimage centres since historical times. The temperature of water recorded in these springs varies from 40°C to that of steam. Some of them are being exploited as a source for geothermal energy.The purpose of this study is to measure radon and helium activity in the thermal springs of Himachal Himalaya. Radon is estimated in the soil and thermal waters using alpha spectrometry and scintil1ometry, respectively. The radon activity is maximum (716.3 Bq/L) in thermal spring (3) at Kasol and minimum (15.9 Bq/L) in a natural spring (bauli) at Takrer Radon concentration is highly variable in the Parbati valley with minimum value of 2230±430 Bq/m3 recorded at Chhinjra on the banks of river Parbati and a maximum value of 57700±2050 Bq/m3 at Dharmaur, the site of uranium ore exploitation by the AMD(DAE). Helium is estimated in the thennal springs by using a Helium Leak Detector (sniffing technique). The radon and helium contents of Kasol thermal springs are correJatable with high radioactivity in the soil of the area as revealed by Alpha Guard survey in the environs of Parbati valley. The helium content recorded in thermal springs is found to vary between 15-90 ppm.
Radon and Helium are well established as geochemical precursors for earthquake prediction studies. Helium/Radon ratio seems to be a better predictive tool for earthquakes in comparison to individual radon and helium precursors.

Fission track ages of 10 samples of muscovite and biotite collected from different areas of Paddar Valley, Kishtwar (J and K State, India) have been determined. The mean ages obtained for this region for muscovite and biotite are 6.9±1.4 and 38.2±4.2 m.y, respectively. The micaceous minerals have been found to contain low concentration of Uranium ∼ 10-10 atom/atom. The f.t. ages correspond to the Tertiary era of the great Himalayan range and agree very well with the f.t. ages determined for the Himalayan orogeny.Full Text

Perhaps, India is the only developing country in the world whose constitution has adopted, after the 42nd amendment in 1976, the inculcation of scientific temper as a fundamental duty of its citizens: 'to develop the scientific temper, humanism and spirit of inquiry and reforms'. In 1981, a statement on scientific temper was issued by a group of intellectuals led by P. N. Haksar, which evoked support as well as criticism from different quarters.Full Text

The DA VIET Research Centre was established in January 2008 to promote research in interdisciphnary area of Nanotechnology. Universal Scanning Probe Microscope (Model NT-MDT Solver PRO M4) was imported from Russia and installed in August 2008. Hind High vac Thin Film coating unit was installed in October 2008. Thus DAVIET became the first engineering institute in North India to establish a well furnished nanotechnology laboratory. Our thurst area of research is fabrication of Quantum Dost and Nano wires for use in nanoelectronics and Opto-electronics. Template synthesis of Quantum Dots and Nanowircs has been achieved by using Anodic Alumina membranes and Polymer membranes of pore diameter varying from 20-200 nm. The electrochemical cell fabricated in our laboratory has been used to grow copper nanowires of 200 nm using an electrolyte with a composition of 20gm/100 ml CuS04.5H20 + 25% of dilute H2SO4 at room temperature. Using Reverse Micelle technique, nanorods of Barium carbonate and barium oxalate were synthesized along with nanocrystals of Iron oxalate. Cadmium sulphide nanocrj'stals and needles have been grown using micro-emulsion technique using different co-surfactants, (characterization of grown using micro-emulsion technique using different co-surfactants. Characterization ol"grown nanostructures has been done by using SEM, TEM and XliD.- Applications of Conductivity Cell in Pollution Control

Public interest and concern about environmental radiation has increased during recent times although radioactivity and X-rays were discovered during the last decade of the 19th century. The sources of environmental radiation are both natural and artificial; the bulk of average annual effective dose (2.4 mSu) being contributed by natural sources of radiation including radon and cosmic rays. The first demonstration of environmental contamination due to artificial radioactivity was the Atomic bomb explosions of Hiroshima and Nagasaki. Radiation accidents have been almost nil at accelerators but the most dramatic episode concerning reactor was the Chernobyl accident on 26 April, 1986. Reactor accidents and nuclear explosions have created a media-hype and a 'nuclear neurosis' among the general public to veto setting up of any nuclear facility in the neighborhood or even in remote areasKeywords

A new branch of Space Science Research focusses on studies on Tektites, Meteorites and moon rocks, the trio with codename XTM (Extra Terrestrial Materials). Theory of Extra terrestrial origin of Tektite has been weighed against the hypothesis of terrestrial origin. Distribution of Tektites on earth, their composition and age have been discussed. The importance of studies on meteorites both in the field of cosmology and origin of life in space has been pointed out. Moon rocks reveal the internal constitution of moon and its age. How those studies help solve some basic questions about the nature of magnetism and life history of solar system etc have been pointed out.Keywords
