Gamma Rays in Radiotherapy 8B Lae Eun Kim In this unit‚ we learned that there are 7 types of radiation of the electromagnetic spectrum – gamma rays‚ x-rays‚ ultraviolet‚ visible spectrum‚ infrared‚ microwaves and radio waves. With different wavelengths‚ they each have different properties and uses. Gamma rays are the radiation with the smallest wavelengths – 10-12m to 10-10m – and the most energy and the most danger of any wave in the electromagnetic spectrum. Radiotherapy‚ a treatment the use

Paul Zindel tells this type of scenario in his play The Effect of Gamma Rays On the Man in the Moon Marigolds. There are three characters in his play‚ Beatrice‚ the mother‚ Ruth‚ a daughter‚ and Tillie(Matilda)‚ the other daughter. Beatrice raises Ruth and Tillie in verbally abusive environment.

use of X-Rays in Modern Dentistry Dentistry is increasingly becoming a major part of people lives in today’s society‚ being taken for granted and often little thought about. As technologies advance treatment becomes cheaper‚ quicker‚ and the outcome becomes more aesthetically pleasing and longer lasting. As braces‚ dentures‚ crowns‚ procedures and techniques change and improve at an alarming rate‚ one aspect has remained the same for a longer period of time. This is the use of X-Rays. X-Rays have been

Applications of X-Rays We see X-Rays all the time in television‚ science fiction novels‚ and comic book superheroes‚ but what is fact and what is fiction? By examining their makeup‚ history‚ modern applications‚ dangers‚ protection‚ and even possible future developments we can understand these scientific marvels far better and more accurately than watching an episode of Star Trek or reading a Superman comic. First and most important is to analyze why an X-ray works and what it is. These “rays” are high

outside factors‚ it changes to the much more stable Tc-99‚ with a half-life of over 210‚000 years. Technetium-99m is used as a radioactive tracer which can be taken orally or injected and can be used to detect internal blockages with the use of a gamma camera. With such a short biological half-life of one day‚ Tc-99m is well suited for scanning procedures that can collect data quickly and doesn’t

millions of times annually. Approximately 85% of diagnostic procedures in nuclear medicine use this radioisotope. Making it the most common radioisotope used in diagnosis. Technetium-99 is used as a radioactive tracer and is detected in the body by gamma cameras. Technetium-99 is produced by bombarding Molybdenum with neutrons‚ producing Molybdenum-99. This then goes through a Beta decay with a half-life of 66 hours and produces Technetium. Technetium-99 isn’t stable and therefore turns into Ruthenium-99

elements are found to be radioactive. They are categorized as alpha‚ beta and gamma radiations. Alpha particles are positively charged helium-4 nuclei ‚ beta particles are high energy-high speed electrons while gamma rays unlike alpha and beta radiation have no mass and charge and are short electromagnetic waves consisting of high energy photons. While alpha and beta radiations have low and moderate risk of damage‚ gamma rays can cause severe damage to internal organs and even death on skin exposure

Technetium has an atomic number is 43 so it has 43 protons and 55 neutrons. On periodic table‚ it’s located on Group 7‚ Period 5‚ and Block d. It has an atomic mass of 98. According to Aufbau Principle and Hund’s rule the full electron configuration of Technetium is 1s22s22p63s23d104s24p64d55s2 and condensed electron configuration of Technetium is [Kr] 4d55s2. First Ionization energy of Tc is 702 kJ mol 1 and second Ionization energy is always higher so it is 1470 kJ mol 1. (Winter‚ M) Technetium
