CHAPTER 1 INTRODUCTION Background of the Study Protecting the patient from unnecessary radiation exposure include not only the Cardinal Principles of radiation protection‚ but also the behaviors of imaging personnel towards each patient. It is often asked‚ "Why do we need to discuss patient protection when it is the patient who is being imaged and therefore being exposed to radiation?" "And is not all radiation exposure made within safe limits so that patient protection is not really possible?" The

About Radiation: Radiation is an energy that is transmitted in the form of waves or tiny particles. These are electromagnetic waves‚ which are classified as ’ionizing radiation’ and ’non ionizing radiation’. Electromagnetic radiation is when an object gives out electromagnetic radiation. For example when you on a torch light‚ the light is an example of radiation. Ionising radiation has more energy than non ionising radiation. Therefore it is enough to cause chemical changes by breaking chemical

Radiation therapist was one of the options listed. I read the description and I fell in love! I knew from that moment on that being a radiation therapist is why I was put on earth. I want to become a radiation therapist because I want to help people in their time of need. Being a radiation therapist would be more than just a job for me. It is a way of giving back and knowing that I am doing something

treatment with radiation I am for the use of radiation because it can be used in many good ways. My sub group is medicine. I am researching a radiation treatment used for helping cancer patients. This is a good use of radiation because it kills the cancer cells and may even cure the cancer. It doesn’t always cure it but it will slow the process down. One reason radiation therapy is used‚ is to destroy the cancer cells. It is also for shrinking tumors. Tumors are mostly cured by the radiation. It can also

Conduction Conduction Conduction is the transfer of thermal energy between regions of matter due to a temperature gradient. In the engineering sciences‚ heat transfer includes the processes of thermal radiation‚ convection‚ and sometimes mass transfer and often more than one of these processes occurs in a given situation.Shaun Prado 8F Shaun Prado 8F Steady-state conduction Steady state conduction is the form of conduction.

PHY 114: General Physics Laboratory Lab 1: Absorption of Nuclear Radiation 09/04/13 Abstract Nuclear physics was practiced to find the value of tau. After 8 trials of using a G-M counter and 8 different mass thicknesses of polyethylene‚ a graph was formed and tau was calculated to be 0.1931 cm^2/g‚ an error of 3.57% from the accepted value of 0.2 cm^2/g. Experiment was also used as an intro to using basic lab equipment‚ computer programs and calculating errors. With many different

alternative career path would be to become a Radiation Therapists. A radiation therapist is a person who treats cancer and other diseases by administering radiation treatments the patient. I choose this line of work because I enjoy helping and working with people. If my first career path doesn’t work out‚ I still want to continue to work with people. I still want to achieve my goal of making a difference in my community. According to Bls.gov‚ radiation therapist made a median annual wage of $80

PHY 114: Absorption of Nuclear Radiation Abstract: The purpose of this experiment was to determine the mass thickness attenuation factor for beta rays when they pass through polyethylene sheets of varying thicknesses. This was done by using an apparatus that measured the seven different intensities and then taking these values‚ putting them through a number of calculations and finally generating a graph of ln(I_corr) versus the thickness of the polyethylene sheets. Once this graph
