Ionizing radiation

Introduction The purpose of this lab is to find the most efficient way to capture energy from a combusted chip using a calorimeter. We made a basic calorimeter by using a steel can. Through out our lab we made modifications to the calorimeter to increase the percent of energy captured by the water. Literature Review Kinetic energy is the energy of motion. The kinetic energy of an object is energy that is being used. Potential energy is stored energy that it is not in motion, but has…

that therefore the amount of radiation produced by the phone is harmful to you. Use research to support your evaluation of the scientific claims made regarding your device. 2 Discusses scientific claims or uses of the technology utilized by the device. A scientific claim made about cell phones is whether or not radiofrequency energy exposure possibly causes cancer or other negative health risks or effects. 4 Cell phones emit an electromagnetic, non-ionizing form of radiation as radiofrequency…

communicated to the radiologist to ensure that they are not contraindicated for the procedure. Furthermore, the possibility of pregnancy has to be ruled out in order to avoid unnecessarily exposing the developing baby to the consequential effects of radiation. The patient is either placed in a supine or prone position into the CT scanner and has to remain still during the procedure. There is an advantage in the prone position, because it allows for better assessment of urinary stones at the…

of natural radiation daily, even pregnant women. However, during pregnancy getting a medical x-ray and receiving any man-made radiation can be harmful to the mother and the unborn fetus as well as the technologist performing the examination. Let’s explore and discuss the effects that radiation can have on the pregnant patient, the unborn embryo/fetus, the pregnant technologist, and the protective or precautionary measures that can be taken to reduce as much harm as possible. Radiation can have…

Discuss the advantages of a database management approach to the file processing approach? Give examples to illustrate your answer. According to our text, database management is the process of storing data. In the early days of computers, they would use data resource management to store information in a specific location. This process was very inflexible and extremely costly. Instead, we use database management today. This process allows us to consolidate the data, and integrate it into many…

I chose the topic MRIs. I will discuss the following topics, what an MRI is, what is an MRI used for, and How should you prepare for an MRI and the risks and benefits. Magnetic resonance imaging (MRI) is an examination that uses a magnetic field and three dimensional detailed anatomical images to take pictures of the inside of the body. In many cases, MRI gives different information about structures in the body that can be seen with an ultrasound, X-ray, or even a computed tomography scan or as…

every three people will develop cancer in their lifetime and over one half will require radiation as part of their treatment. Radiation oncology is a medical specialty that focuses on the use of ionizing radiation to treat cancer and other diseases (including benign ones). It is one of the three primary specialties (the other two being surgical and medical oncology), involved in the treatment of cancer. Radiation can be administered as a curative modality, either on its own or in combination…

growth and possible destruction of surrounding normal cells. The International Agency for Research on Cancer has classified some 60 substances and processes as probably or definitely carcinogenic in humans. Some examples are as arsenic, asbestos, ionizing radiation, ultraviolet rays, x rays, and many derivatives of coal tar. Metastatic cancer is cancer that has spread from the place where it first started to another place in the body. A tumor formed by metastatic cancer cells is called a…

fusion, and radioactive decay. Farther into book Ferguson gives background information on nuclear energy and the health risks that can develop from it. People exposed to too much ionizing radiation over long periods of time are at a higher risk for developing cancer; however, the human body can fight off ionizing radiation in low dosages, so containing the amount of…

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…
