Epidemiology of Chemotherapy and Radiation Causing Premature Aging: With the results of cancer treatments that have caused premature aging, Doctor Melissa Hudson of the St Jude Children’s Research Hospital stated that: “cataracts were present in over 20 per cent of those who had received eye radiation, or had been treated with glucocorticoids or busulfan”, and “the presence of heart valve disorders in those aged 40 who had received chest radiation increased in prevalence from 5.7 per cent to…

Collectively the pennies represent a radioactive sample, and each penny is an atom. Because each penny has a 50% chance of decaying it can represent a radioactive atom. When the atoms are grouped together it becomes a sample of a radioactive element. For the simulation to work one has to assume that a coin toss has a 50% chance of landing on heads and a 50% chance of landing on tails. If this is not true then the trial will not be a true half-life because more or less than half of the atoms…

The Life Of Richard Pryor Who was Richard Pryor, some people might ask? Well he is an African American Actor/ Comedian. One of his most famous quotes is ‘If I thought about it, I could be bitter, but I don't feel like being bitter. Being bitter makes you immobile, and there's too much that I still want to do. Richard Pryor is known for his colorful language during his live comedy shows , and he is highly influential , and always controversial towards African Americans. He has also been…

There are several areas in the natural world where the process of exponential decay arises from random processes. Whenever a material decays at a rate in proportion to its amount, this material represents the process of exponential decay. Exponential decay can be described using the mathematical model y=a×e^(-bx). A prominent example of naturally occurring random exponential decay is the process of radioactive decay. Some isotopes of nature are considered radioactive due to a specific…

Colon cancer and rectal cancer is considered a disease developed in the tissues of the lower part of the gastrointestinal system. It typically starts in the inner lining of the large intestine as an uncontrolled growth of tissue called polyps. Together they are referred to as Colorectal Cancer. Colon cancer or bowl cancer originates in the terminal part of the large intestine whereas rectal cancer originates in the rectum which is the last portion of the large intestine to the anus. They are…

Introduction Food irradiation has been called “today’s pasteurization,” as the safety and quality benefits it offers are similar to those of pasteurization for milk in the early 1900s. (Palmer). However, there have been pros and cons associated with this process, and its increased use has also increased the debates over its benefits and safety. Economic impact (Pros/Cons) Food irradiation could potentially have a huge positive impact of lowering the costs of food. One of the benefits is a…

treat brain tumours, and certain types of cancer through “radiation delivered from a tiny source implanted directly into or next to the tumour. These sources produce gamma-rays, which have the same effect on cancer cells as X-rays. This treatment reduces damage to surrounding healthy tissue, thereby limiting side effects” (Radiation oncology, sec. 1, par. 1). However, though small, there are risks attached to this certain type of radiation treatment, according to Dr Ananya Manda the immediate…

(photon radiotherapy). One primary difference between the two therapies revolves around the way in which radiation passes through the patient’s body, which has made serious improvements that some people may not be aware of. Photon radiotherapy actually uses radiation with the X-ray beam which passes through the patient’s whole body, while the newer, more beneficial process utilizes radiation to…

works to fight cancer is radiation therapy. Radiation therapy is more effective than non-traditional treatments because it kills cancer for the better, even though it is a little at a time, after therapy in a few weeks or months. Yet it still kills cancer at hand rather than not at all. Depending on how much radiation a doctor uses on a patient, depends on if the cancer cells die and the patient is free of cancer. It all depends on the doses given, “At high doses, radiation kills cancer cells or…

Discussion and Scientific Explanations Colors help most people describe what different objects look like. When white light hits an object, in most cases, the object will absorb all of the wavelengths, except for one group. This group of wavelengths is then reflected off of the objects. The cones and rods in our eyes will then pick up this wavelengths and then the brain sees them as “color”. The reason that solutions have colors is because electrons in the chemical’s 4d orbital are jumping…
