The aim of the present study was extended from obtaining information about the interaction of gamma rays with Makrofol DE 7-2 track detector to introduce the basis that can be used in concerning simple sensor for gamma irradiation and bio-engineering applications. Makrofol polymer samples were irradiated with 1.25 MeV (60)Co gamma radiations at doses ranging from 20 to 1000 kG y. The modificati...

Gamma irradiation treatments have commonly been applied to induce variation in plant genetic improvement programs. The of nyawai (Ficus variegata Blume) is urgently needed mainly break the seed dormancy, increase seedling growth, and for selecting desired traits. This research aimed assess effect gamma doses on germination, leaf morphology Ficus variegate Blume. experiment's ranged from 5-240 G...

objective(s):cervical cancer is a malignancy that is the second most common cause of death from cancer in women throughout the world. paederus beetle (paederus fuscipes) extract (pbe), contains bioactive compounds such as pederine which has cytotoxic properties and blocks dna and protein synthesis at very low concentrations. in this investigation we tried to determine the effects co-treatment w...

When given in the presence of gamma interferon (IFN-gamma), otherwise nontoxic doses of lipopolysaccharide (LPS or endotoxin) become highly lethal for mice. The mechanisms of this synergistic toxicity are not known. We considered the possibility that an interaction between the LPS-induced NF-kappaB and IFN-gamma-induced JAK-STAT pathways at the pretranscriptional level may enhance the LPS-induc...

Allograft safety is contingent on effective sterilization methods such as gamma irradiation. However, recent clinical studies have associated gamma irradiation with decreased graft strength and increased allograft failure rates, despite data that shows no deleterious effects to soft tissue biomechanics at gamma doses between 1.46 and 2.18 mRad. The objective of this study was to compare the bio...

gamma rays pose enough energy to remove electrons from atoms of absorbing material including human body and adversely affect human health. the external exposure of human beings to natural environmental gamma radiation normally exceeds that from all man-made sources combined. therefore, we monitored gamma dose rate in indoor environments and estimated corresponding annual effective dose in selec...

High linear energy transfer (LET) heavy charged particles have previously been applied clinically to human cancer radiotherapy because of their excellent physical properties of selective dose distribution and higher relative biological effectiveness (RBE) for human; however, such an approach has yet to be applied to cat patients. The present study investigates the biological effectiveness of lo...

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...

Satisfactory discrimination between the neutron and gamma components in a mixed neutron-gamma field is one of most important objectives dosimetry. One common techniques for estimating dose fields two peak method. This method has been applied using dosimeters such as LiF:Mg,Ti, but present work, 6LiF:Mg,Cu,P dosimeter used, whose thermoluminescence sensitivity much higher than LiF:Mg,Ti dosimete...
