Radiation

Radiology is the science of utilizing varying forms of high-energy radiation such as x-rays, for the diagnosis of injury and disease. An x-ray technologist is the medical professional responsible for the x-ray procedure. The technologist has many roles and is obligated to follow protocol while completing daily responsibilities. One of the main roles of the technician is communicating with the patient, this involves but is not limited to: greeting the patient, educating the patient on the…

stands of charcoal black hair that were woven into the hairbrush. Radiation therapy uses high doses of radiation to kill cancer cells and shrink tumors (“American Cancer Association”). One of the women I met at the walkathon had radiation therapy. They go through a machine that kills the cancer cells using radiation. Radiation therapy doesn’t only kill cancerous cells through. The woman that I met at the walkathon said that radiation therapy can impact reproductive organs because they are very…

you ever thought what it would be like if you were in the position of someone with cancer? Has it ever occurred to you that they do wish they had gorgeous locks of hair? Well, they certainly do and hair loss may be the side effect of chemotherapy, radiation therapy, and stem cell transplants. These treatments can cause hair loss by harming the cells that help hair grow and during this process hair may fall out entirely, slowly, or in sections. Hair loss related to cancer treatment is usually…

which control how skin cells grow and divide. If these genes become affected, they’re no longer able to function properly due to the damage caused by the radiation and may become cancerous as the genes are unable to repair the damage. Melanomas develop in the skins’ pigment cells (Melanocytes), which produce melanin to protect the skin from UV radiation. If left untreated, melanomas will grow very quickly and become life threatening in as little as six weeks because the cancer spreads into vital…

The Sun and Our Star - Have you ever questioned as to how and why we are able to dry our clothes in the summer, and to be able to heat food and treat our water? - This all thanks to the sun - Without the sun, we all would be dead, it gives us light, heat and energy to heat up the Earth - Most of the energy stays inside of the sun because of its gravitational pull, and all small amounts leave the surface in the form of radiant energy Type of star: Age: Yellow dwarf 4.5 Billion Years…

detected using electronic devices. Important terms that will be discussed in this paper are ultraviolet light, photochromism, chemical reactions, and absolute zero. Relating to electromagnetic radiation having wavelengths shorter than those of visible light but longer than those of x-rays. Ultraviolet radiation is emitted by the sun and some of its absorbed by the sun and some of it is absorbed by the o-zone in the atmosphere. Too much exposure to ultraviolet light can be can lead to sun burn,…

After students have met the education requirements of a foundational program and have been certified in either; Radiography, Nuclear Medicine, or Radiation Therapy, only then are students able to start working towards post-primary certifications. The certification and registration is overseen by ARRT (American Registry for Radiologic Technologist). Candidates for CT certification are required to perform…

1.Magnetic resonance imaging uses the property of Nuclear Magnetic Resonance to take the image of nucleus has magnetization of its own and in MRI scanner patient is placed between a large magnet. This allows nucleus of atoms to align themselves according to their magnetization which leads to the production of magnetic field which is noticed by MRI scanner. This is how magnetic resonance imaging exploits the magnetics properties of the nucleus. 2. Sound waves are longitudinal waves and they…

Introduction Thermodynamics is an essential concept examined during the construction stage of houses, especially in the countries reaching extreme temperatures, such as Australia. By understanding the physics involved in thermodynamics throughout the construction stage of houses, such as heat transfer involving different colours and thicknesses, it is possible to re-examine the insulation of houses in hot countries. Such a report can lead to finding the most appropriate colour and thickness for…
