Background radiation

discouragingly ineffective and survival rarely longer than 2 years with an average of 10-14 months.In selected cases with stage 1 a radical surgery-pleuropneumonectomy{removal of lung and pleura} may be effective,but long term survival is rare.Primary radiation therapy may be used also. Combination chemotherapy using either single agent or combination protocols have also been used but the outcome remains…

Diagram of Prototype A that consisted of an octagonal prism with a length of 11 in. or 27.94 cm. and height of 10.16 cm., while we created corrugated layers within the prism. We decided to change all the dimensions to centimeters instead of using inches as the units. Tinkercad model of Prototype B that consisted of a hexagonal prism with a length of 27.94 cm., height of 10.16 cm., and sides of the base of 4.445 cm. WIthin the hexagonal prism consisted of 6 equilateral triangles are connected…

the topic of how diagnostic radiology procedures do affect the risk of cancer later in life. The authors of this article compared lifetime data and statistics from the survivors of the Japanese atomic bombs to children who had been exposed to radiation from CT scans. This is how they began their studies in 2008. The researchers…

with a longer wavelength and lower frequency than visible light. (Wikipedia) IR Spectroscopy is a method to identify substances based on their absorption of infrared wavelengths. It is a study of how the molecules of substances can absorb infrared radiation and convert it into heat. (Cole) A machine called an infrared spectrometer applies infrared rays to a substance to record the number of wavelengths absorbed by said substance. (Cole) This works because of covalent bonds within substances.…

The world is full of a multitude of colors that are used for both practical and aesthetic purposes. The colors that are seen when looking at different objects are due to the ability of the compounds in those objects to absorb specific wavelengths of light. In other words, the colors that are seen are the ones that are not absorbed. The wavelengths of light that are absorbed are determined by the electrons in a compound.1 As electrons move around, they can absorb energy and become excited. The…

pinpoint and destroy any cancerous cells within the body by using a special equipment to send high doses of radiation ( MD Anderson Cancer Center). In fact, radiation can be given three different ways which are: • External radiation • Internal radiation • Systemic radiation However, these types of radiation are given by the type, size, and location of cancer within the body. What is more, radiation can also destroy normal cells by making small breaks in the DNA which can cause telomere…

SEM is a kind of microscope to observe the topography of materials. SEM has some advantages: it has a large depth of field and we can observe the 3D image of the sample and analyzing its topography, its magnification range is widely and we could make sample easily because of the X-ray spectrometry, which can determine the elements of sample. When electron beam attack the sample, incident electron will be diffracted and change the direction or even loose some energy. During this process,…

The therapeutic properties of qigong have been found to improve the regulation of the respiratory system, improved the physical function of the body’s self-control, and boosted the massaging effect on the abdominal cavity organs, served to correct the abnormal organ reactions, and improved the activities of the cardiovascular system, central nervous system, cerebral cortex and regulated the metabolism process. Additionally, practices on qigong have shown a considerable amount of improvement in…

the ionic charge, it cannot exit from the cell unless it decays. So, the radiolabeling of tissues with high glucose uptake is enabled with the using of FDG-PET. Some other examples of glucose-using cells are brain and liver. Usually, the effective radiation dose is…

summer days. The advanced fabric would aloe IR radiation to escape through the fabric easily, and prevent the body from overheating. Furthermore, researchers have produced a nanoporous fabric that can release body heat, instead of…
