The purpose of the research was determine the effects of gamma ray on seed germination, seedling height and root length of Rice (Oryza sativa L. spp. Indica cv. MR219) to identify the Lethal Dosage of the radiation. Paddy seeds of MR219 were exposed to different doses of gamma radiations viz 50,100,150,200,250,300,350,400,450,500,600,700,800,900 and 1000 Gy using 60Co as the radiation source. T...

In this research work, effect of carbonate content on EPR response of gamma irradiated HAP were investigated. The carbonated HAP samples were prepared by substitution of carbonate group into HAP structure via chemical method. Fourier Transform Infrared (FTIR) spectroscopy and X-ray diffraction (XRD) methods were used to investigate the structural changes of the samples. Then, the samples were s...

After several years of using solar cells, its electrical parameters are degraded. in this paper, to simulate aging, cells were exposed the different doses gamma radiation. The (I–V) characteristics silicon studied before and after irradiation. Experimental results showed that parameter panel such as short circuit current, open voltage, efficiency decrease with increase doses. As well as, depend...

Most studies of radioadaptive response (RAR) in vivo have revealed its effective induction both by chronic and single irradiation a human organism with low doses. The classical way the for-mation RAR on peripheral blood lymphocytes (PBL) was noted as occupationally irradiated personnel residents areas increased natural or man-made accidental high background radiation. In some studies, liquidato...

The production of dead (apoptotic) cells by low doses of gamma-rays was independent of dose-rate between 0.27 and 450 cGy per min. The r.b.e. for doses of 14.7 MeV neutrons between 1 and 15 cGy was about 4, and for neutrons generated by bombarding a beryllium target with 600 MeV protons the r.b.e. was about 2.7. The dose-incidence curves for all three radiation types reached a plateau at about ...

hyssopus of­ficinalis l. is one of the most important medicinal plants. medicinal herbs are contaminated by microorganisms. conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

     Mutations induced by gamma irradiation are part of improving some important agronomic traits in crops.  Identifying the optimal mutagenic dose is considered to be the most crucial step in trials and generating mutated genetic materials. The goal of this study was to evaluate the effect of different doses of gamma ray (0, 150, 200, 250 and 300 Gy) on some plant early stages traits and bioch...
