Radiation

for breast cancer. She was passionate when she spoke of the care and concern demonstrated by the radiation therapists during her treatments. It was after her treatments that I decided that radiation therapy would be a great profession for me. I could help others going through difficult times while doing something that I thought I would be rewarding. Despite having a personal connection to radiation therapy, another experience during my first year of college has led me to another helping…

meaning of the effects radiation has on the daily life of students from Chavez high school. Many of us don’t know what radiation means let me enlighten your mind in physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium (Google). Radiation is used in our life in different ways and to figure that out we’re going to ask a few students from Chavez to tell us how much they expose themselves to radiation. Purpose…

Essay 1: Adaptive Radiation Adaptive radiation is the fundamental mechanism responsible for the great variety of animal and plant species observed today and that dominated the Earth surface in the past (MacDonald, 2003). In simpler terms, adaptive radiation is the diversification of species to occupy a wide range of ecological niches. The term ecological niche describes the role of a species within its surrounding environment; its interaction with the biotic and abiotic environmental factors;…

infancy, it was common practice for the dentist or dental assistant to help the patient hold the film in place while taking the radiograph, exposing them to unnecessary radiation, repetition of this endangered their health and occasionally led to permanent injury or death. Fortunately, although the hazards of prolonged exposure to radiation are not completely understood, scientists have learned how to reduce them drastically by proper use of fast film and digital sensors, safer x-ray machines,…

Data Analysis: Microwave Radiation and Plant Growth How does radiation affect the growth of plants? If seeds are exposed to microwave radiation then the growth process will increase. Get three seeds of the same type of vegetable (cucumbers were used in this experiment). Before planting, microwave plant cell #2 for 15 seconds and plant cell #3 for 30 seconds (plant cell #1 is not microwaved at all). After planting them, see the difference in the growth of these seeds over 35 days. The…

Since the first planet orbiting a star other than our Sun was discovered almost 20 years ago, astronomers have detected over 3,000 exoplanets. Going forward, exoplanetary scientists have two major goals: detecting smaller, more Earth-like planets, and characterizing particular planets of interest. With the advent of the extremely large telescope (ELT) era soon approaching, these two goals will become increasingly intertwined as better instruments give us the power to study the atmospheres of…

I. Intraoperative Radiation therapy: Also known as IORT II. Problem: Breast cancer is the most common type of cancer for women. It is when there is a lump in the breast that contains cancer cells. Some lumps do not contain cancer cells though. The doctor will have to diagnose someone with breast cancer. Breast cancer is one of the top ten leading causes of death in females. Even males can get breast cancer. At least 200,000 women are diagnosed with breast cancer each year. In 2011 40,000…

Cancer has many forms of treatment, but the two that are known to most are chemotherapy and radiation therapy. Chemotherapy is the use of drugs like cytotoxic and others, where as radiation therapy is the use of x-rays or other similar forms of radiation to cure cancer. Arguments can and more than likely always arise that one form of the two treatments is more beneficial and effective than the other. Considering this, the type of treatment that may be used can differ for each type of cancer,…

Mutations of Penicillium notatum When Introduced to Ultraviolet Radiation in Different Environments Introduction DNA is composed of two strands composed of polynucleotides arranged in a double helix formation composed of four nucleotide subunits: adenine (A), thymine (T), guanine (G), and cytosine (C). Each base must form a hydrogen bond with its respective compatible base, therefore adenine always bonds with thymine and guanine always bonds with cytosine. DNA is used to…

Usually, when children have malignant brain tumors, they will need radiation therapy to try to stop the malignant cells from spreading. Doctors try their hardest to postpone radiational therapy in children as it may generate long-term brain effects. When radiation therapy is used, the radiational energy transmitted to the tumor area can affect abnormal tissue as well as normal tissue, which can induce problems. The more tissue area that the doctors choose to radiate, the higher the chance…
