Exposure Buildup Factor Studies in Some Soils

An attempt is made to generate effective atomic number, exposure buildup factor (EBF) in the energy region 0.015-15.0 MeV up to a penetration depth of 40 mfp for some soils. The five parameters geometrical progression (G-P) fitting approximation has been used to calculate exposure build-up factor (EBF). The generated exposure buildup factors has been studied as function of incident photon energ...

Spectroscopic and Electrochemical Studies of Imogolite and Fe-Modified Imogolite Nanotubes

Carbon nanotubes and other forms of carbon nanoparticles, as well as metal nanoparticles have been widely used in film electrochemistry because they allow for the immobilization of larger amounts of catalyst (either biological or inorganic) on the top of the modified electrodes. Nevertheless, those nanoparticles present high costs of synthesis and of separation and purification that hamper thei...

Release of 222Rn from some soils

Measurements have been made of 222Rn release from diverse soils in the region surrounding Málaga, Spain. These flux measurements were carried out by two methods. A direct method using a static chamber technique and another indirect method obtained from concentration profile measurements of 222Rn in the soil air. The effects of meteorological variables and other parameters on 222Rn flux were stu...

Some Investigations on Cracking Characteristics of Soils

Fine-grained soils, in particular, expansive soils are prone to cracking. For these soils swelling-shrinking potential is quite high and hence they exhibit adverse affect on overall stability of geotechnical structures. This phenomenon may also be responsible for alteration of various engineering properties of soils such as hydraulic conductivity, water and leachate penetration, solute transpor...
