Radionuclide

The beta – plus radiation is one of the types of decay. The structure of a positron is where the proton of the beta- plus is found in the radionuclide. The nucleus then makes neutrons which then give out positrons which are beta- plus particles. When the neutron transforms into a proton, the proton stays back in the nucleus and the electron that is formed moves away with a lot energy. As the…

Urinary tract infection is one of the most common bacterial infections in childhood, affecting up to 8 % of girls and 2 % of boys before the age of 11 years. The presentation of UTI varies with age; in infancy, symptoms are often generic including fever, lethargy or irritability, vomiting, diarrhea, poor feeding, failure to thrive, septicemia and febrile convulsion. Several textbooks mention prolonged neonatal jaundice as one symptom of UTI. Jaundice is very common in newborn babies occurring in…

Amazing, the survival rate of pregnancy among expecting mothers has improved significantly in over the years. This is due in part of pregnancy being diagnosed early enough today. This is made possible through radiographer using ultrasound machines. Having seen my wife went through all different kind of scans during the birth of my son and how the new technology helped detected early pregnancy problems, I knew that I wished to follow the part and work in a medical environment helping doctors and…

Analysis Three Bentonite properties, which makes it a unique buffer material for nuclear disposal applications are discussed in the following: 1) Thermal conductivity Thermal conductivity is the rate at which heat can be transferred through a certain material. It is also expressed as the flux of heat, which flows per unit time through a unit distance with a temperature gradient of one degree per unit area. Thermal conductivity, like other tensor parameters, has different values in different…

Fluoride can stain teeth and give you dental problems. According to M.J. Blackstone from http://www.newrinkles.com, “Potential health effects from microorganisms, disinfectants and their byproducts, inorganic and organic chemicals, and radionuclides include everything from eye/nose irritations to kidney and liver disease.” Bottled water unlike tap water can have healthy and safe additives in it, like electrolytes, minerals, and vitamins according what Kristeen Cherney wrote in the article…

IRRADIATION Food irradiation is the processing of food products by ionising radiation in order to control food borne pathogens, reduce microbial load and insect infestation, inhibit the germination of root crops, and extend the durable life of perishable produce (International Consultative Group, 1991). Application of ionizing radiation results in the radiolysis of water. This triggers the development of species such as OH−, hydrated electron and H+, which can then induce several chemical…

The concentrations of difference between the membrane phase and feed phase based on the mechanism of mass extraction. In the case of feed solution represented radioactive simulated waste solution and dissolved in 0.5M HNO3. In the feed phase decreasing with H+ concentration. pH values at 2.5 into 5.5 in the feed phase. Fig,s(5a-5c). Shown the effect of hydrogen ion concentration in the feed phase and studied of pH range 2.5-5.5 for 0.5M HNO3. Stripping solution of 0.05M of EDTA. Initial…

biogeochemical cycling of carbon, hydrogen and variety of trace metal elements. Nitrate(NO3-)reducing bacteria are important for bioremediation purpose. It acts as oxidizing toxic organic compounds to carbon dioxide (CO2) and reduce immobilizing radionuclides…

Breast cancer is the most commonly diagnosed cancer worldwide for women in 140 out of 184 countries. Breast cancer rates have continued to rise over the years with the current statistic stating one out of every eight women will develop breast cancer in their lifetime. It is the second leading cause of cancer death among women.1 Since 1990, there has been a decline in the death rates from breast cancer due to improved screening, early detection, increased awareness, and continually improving…

Chernobyl On April 26, 1986 in a town just north of Kiev, Ukraine, lies the Chernobyl Nuclear Power Plant, and on this unfortunate day one of the nuclear reactors failed, causing numerous deaths and many more problems to the areas surrounding this nuclear plant. In this paper the history of Chernobyl will be examined and how it happened, along with the health effects related to radiation exposure, environmental effects, and what its’s like at Chernobyl today. Chernobyl had a total of four…
