ABSTRACT: The dose and dose-rate is the basic physical factors determining the effects of ionizing radiation on biological systems. It ispredicted that an employers exposed to low dose mayspendfor several months in a radiation field without becoming alarmed. The study aimed to discuss the evaluation of low dose ionizing radiation (IR) effect on some blood components and liver enzymes in radiological staff. Peripheral blood cells count and liver enzyme (SGOT and SGPT) were determined for 11 workers (divided into 2 groups) pre- and post-irradiation. An attempt to explain the blood changes resulting from both irradiation and time is given. There was a strong liner correlation between............

ABSTRACT: In this paper, we proposed the smallest particles of the composition of the earth, the role of hydrogen atoms, according to the gravitational wave theorem, the variable field theorem and mathematical modeling analysis. The roles and relations of protons and neutrons are elucidated. Any material is a combination of hydrogen atoms, and finally three kinds of material basis which form the earth were prompted. New principle of inter atomic periodic law was proposed............

ABSTRACT: It is important to measure the bulk-etching rate for any solid state nuclear track detectors, because they have an application in different fields of sciences. The effect of gamma rays emitted from 60Co source with different doses on LR-115 detector was studied. The bulk etching rate of the detectors was measured before and after irradiation using gamma source. From the results the values of the bulk etching rate of LR-115 without gamma rays have been 3.10 μmh−1 and that under gamma irradiation with different doses were ranged from 4.60 to 8.77 μmh−1. This means that the values of the bulk etch rate increase with increasing gamma doses.

ABSTRACT: A simple acoustic measurement method has been applied to demonstrate Poisson distribution of bubbles sparkling at a water surface. The quality of sparkling water has been determined by quantifying the characteristic time of decay of number of air bubbles sparkling at the surface of water served to consumers. The average sound frequency of the bubbles at sparkling has been found dependent on the chemical composition of the water (carbon dioxide and minerals concentration). The acoustic measurement method proved to be fast and reliable for determining the quality of appearance of served sparkling water.
