No doctors have been able to diagnose him‚ because he is not sick with a normal sickness‚ he has radiation poisoning.

Chapter 1 Introduction According to Bushong (2009)‚ radiation is an energy that moves through space or matter at a very high speed. This energy can be in the form of particles‚ such as alpha or beta particles‚ which are emitted from radioactive materials‚ or waves such as light‚ heat‚ radiowaves‚ microwaves‚ x-rays and gamma rays. He also mentioned that radioactive materials which is also known as radionuclides or radioisotopes are atoms that are unstable. So‚ there is a tendency for unstable atoms

involves the use of x-rays‚ a form of ionizing radiation‚ CT scan is used to detect and diagnose the presence and recurrence of tumors in human body and also provides the stage of a cancer. Several case studies have shown that CT scan can be effective in both colorectal cancer and lung cancer screening. Exposure to ionizing radiation is caused to increase the risk of cancer. Children may be at higher risk because usually children are more sensitive to radiation than adults and have a longer life expectancy

July 15 to September 16‚ 2013. Results showed that seeds treated with 10 kr radiation obtained the highest average height of 128.90 cm with 100 % germination and survival. The seeds treated with 50 kr radiation obtained 0% survival rate and the lowest germination rate (70%). Thus‚ irradiation of 10 kr induces mutation to the corn which will give the highest survival rate and germination of the seed while doses of radiation higher than 10 kr will inhibit its growth and decrease germination. Generally

element‚ however‚ unlike elements‚ they feature a differing mass number‚ meaning the amount of protons and neutrons is imbalanced. (Gothard‚ 2004) Sometimes‚ an isotope exists with an unstable nucleus‚ spontaneously emitting excess energy through radiation known as alpha (α) particles‚ beta (β) particles or gamma (?) rays.

gauging. In the area of medicine‚ Cobalt-60 is used in cancer radiotherapy. b) Describe how the radioisotope is made. Radioactive cobalt-60 is produced in a process called activation‚ when materials in reactors‚ such as steel‚ are exposed to neutron radiation. Often isolated neutrons collide into atoms‚ and because they have no charge there is no repulsive force against them. These neutrons turn the atoms into isotopes; in this case typical iron-56 becomes iron-57‚ 58 and then 59. The heavy iron-59 atom

ANALYSIS OF SOLUTIONS One of the effects that ionizing radiation has on the human body is the appearance of cancer. To treat cancer‚ ironically‚ radiation is often used. Radiation treatment is the 2nd most common form of cancer treatment‚ next to surgery. The National Cancer Institute estimates that over half of all cancer patients receive radiation treatment sometime over the course of their illness (Radiation Therapy and You 2). It can be used alone to fight cancer or can be used in combination

interpret information on every organ system in the body. Nuclear medicine is a special branch of medicine or medical imagery. It uses radioactive isotopes that rely on the process of unstable atomic nucleic emission of ionizing particles and radiation to diagnose and treat disease. Radiation looks at both the function and the anatomy of the body to establish a diagnosis and treatment. The tests use small amounts of radioactive material to assist with diagnosis. Radiopharmaceuticals or radiotracers are

Nuclear fusion is also called thermonuclear fusion. Nuclear power plants are powered by nuclear radiation using nuclear fission as heat that produces electricity.
