Isotopes Medical isotopes are used in medicine in three distinct ways: 1. Radioactive isotopes can be injected into a patient‚ and their emitted energy can then be captured on film. The resulting image is an important diagnostic tool. 2. Gamma rays emitted from a radioactive source can be directed onto a tumour‚ destroying the cancerous cells. 3. Radioactive isotopes can be manufactured into drugs. Once injected into a patient‚ the drug will accumulate in a certain part of the body

Norhan Mansour Music 121 Extra Credit Ray Ray is a 2004 biographical film focusing on 30 years of the life of rhythm and blues musician Ray Charles. By the early 1960’s Ray Charles had accomplished his dream. He’d come of age musically. He’d made it to Carnegie Hall. The hit records "Georgia‚" "Born to Lose" successively kept climbing to the top of the charts. He’d made his first triumphant European concert tour in 1960 (a feat which‚ except for 1965‚ he’s repeated at least once a year ever

Nuclear Medicine Nuclear medicine has been around for more than 50 years now and stems from the discovery of x-rays and artificial radioactivity. In 1946‚ nuclear medicine made a monumental breakthrough when radioactive iodine led to the complete disappearance of cancer in a patient’s thyroid. Nuclear medicine became widely used in the 1950’s to measure the function of the thyroid‚ to diagnose thyroid disease‚ and for the treatment of patients with hyperthyroidism. By the 1970’s nuclear medicine

For medical purposes‚ radioisotopes are used diagnosis and research. For food-industry purposes‚ radioisotopes are used to sterilize fresh products (radiation kill parasites‚ pests‚ and bacteria). For industrial purposes‚ radioisotopes are used for x-ray equipment. For space purposes‚ space probes that are required to operate in places far away from the sun‚ the only available solution for the production of heat and electricity is radioisotopes.

Acute Radiation Syndrome Acute radiation syndrome which is also sometimes known as radiation sickness or radiation toxicity is an extremely serious illness that occurs when the entire body (or most of it) receives a high dose of penetrating radiation‚ a dose greater than 50 rads‚ in a very short period of time. Studies in animals and humans exposed to radiation have allowed researchers to describe acute radiation syndrome. The most replicative cells are the most sensitive to the acute effects

What are X-rays? X-rays are a form of radiation that can pass through solid and semi-solid substances. In carefully controlled doses‚ they can be used to capture images of the body’s internal structures. How X-rays work X-rays are a type of radiation. Light and X-rays are similar sources of energy. However‚ light has a much lower frequency than X-rays and is absorbed by your skin. X-rays have a higher frequency and pass through the human body. As X-rays pass through the body‚ energy particles

Energies are many folds‚ they are available naturally‚ and are also made available through science and technology in different ways‚ intended for the purposes we desire. This light that enables us to see‚ the x-rays (which gives us pictures of bones and soft tissue)‚ the gamma and ultraviolet rays (which are used for sterilization)‚ infrared‚ the microwave (microwave ovens and cell phones)‚ radio waves‚ extremely low frequency waves etc. are all packed in the radiation that emanates from the sun.

EFFECTS OF RADIATION Background Radiation is all around us. It is naturally present in our environment and has been since the birth of this planet. Consequently‚ life has evolved in an environment which has significant levels of ionizing radiation. It comes from outer space (cosmic)‚ the ground (terrestrial)‚ and even from within our own bodies. It is present in the air we breathe‚ the food we eat‚ the water we drink‚ and in the construction materials used to build our homes. Certain foods

INTRODUCTION Major of us was seemingly misinformed or not knowledgeable enough about this certain topic‚ The Nuclear Energy and its capabilities. Nuclear energy is a clean‚ safe‚ reliable‚ independent and competitive energy source. Moreover ‘this’ energy can be of great help with reducing and preventing air pollution that can lead and contribute to the greenhouse effect by replacing a significant part of the fossil fuels. Also‚ besides from the fact that it can be the source of our electricity‚

To Mayor Patrick Quinn‚ My name is Santiago Arellano‚ and I am a resident of Broomfield Colorado. I would like to present my opinion on the North Park Hydraulic Fracturing. Hydraulic Fracturing is a very ingenious way of removing oil from the deep Shale‚ which we have been unable to reach. This method‚ also known as Fracking‚ is also very small. It starts out with a drill rig and a holding tank for the first 3 months‚ but then once the well is dug‚ it looks like another oil drill‚ and will continue
