Nuclear chemistry in medicine is very controversial. Many say the dangers of using radioactive materials on human bodies are far more negative than positive. Others strongly agree with the use of radiochemistry in the field of medicine. Nuclear medicine is in the field of medicine by using imaging devices. Doctors use small amounts of radioactive materials called radio tracers that are either injected into the bloodstream‚ inhaled or swallowed. Radiation therapy is also a therapy that uses radioactive

used around 20 million times per year and is a very valuable radioisotope. * Technetium-99m is used to image parts of the body such as the brain‚ bones‚ thyroid‚ heart‚ salivary glands and blood pool through procedures such as SPECT (Single Photon Emission Computed Tomography). * Benefits associated with use: * Technetium-99m’s gamma radiation is easily detected and provides a high resolution which allows it to be highly useful for imaging inside people. * The amount of radiation

RADIOISOTOPES IN MEDICINE ABSTRACT: Nuclear medicine has become fundamentally life-saving as a diagnostic tool in today’s medicine‚ however exposure to radioisotopes has risks. Understanding these risks and making an educated decision is crucial in personal choices regarding medical treatment. This overview of recent and relevant research provides an insight and support to the benefits of radioisotope usage‚ whilst presenting the associated risks. INTRODUCTION: With the discovery

I am always delighted when I am blessed with the opportunity to acquire new information to add to my brain’s knowledge base and Dr. Daniel Amen’s presentation: Change Your Brain‚ Change Your Life did just that. I found Dr. Amen’s presentation to be very informative and I gathered a plethora of knowledge on the human brain that I had no prior knowledge of. I was particularly intrigued by the SPECT scans which looks at blood flow and activity patterns in the brain. I was not aware that you could improve

A. Converting photosynthesis rate from volume of oxygen produced per gram leaf per minute to mol CO2 fixed per area of leaf (in m2) per second. B. Why would one want to express photosynthesis rate as µmol CO2 m-2 s-1? What is the advantage. Answers: A. How to convert photosynthesis rate from volume of oxygen produced per gram leaf per minute to mol CO2 fixed per area of leaf (in m2) per second. Photosynthesis rate can be measured either by seeing how much oxygen is produced by a leaf

phenomenon of redshift is conventionally explained by the well-known “Doppler effect”. But according to the book “QED: The strange theory of light and matter” by Nobel Laureate Richard Feynman Redshift occurs due to the quantum mechanical propagation of photons. The Problem:Edwin HUBBLE discovered that light from distant stars exhibits longer wavelengths or reduced frequencies than that from similar radiation sources on Earth. All specific frequency lines in the electromagnetic spectrum of distant cosmic
