beta radiation not spreading far around the body‚ this keeps tissue damage mostly limited over the intended area. After the use of iodine-131 by a patient the majority of the radionuclide clears the body after around three days through radioactive decay and also through sweating and urination. For this reason‚ patient isolation is advised due to iodine-131 being a gamma radiation emitter. Radioactive iodine may still be present in small amounts in the weeks after administration due to the thyroid

and so iodine 131 can treat thyroid disorders (e.g. tumours) Iodine 131 has a half life of just over 8 days‚ emits beta particles and gamma rays as it decays. This half life is long enough for it to be transported form where it is produced to where it needs to be used but it is also short enough to minimise patients exposure to radiation It decays into non-radioactive gas‚ Xenon 131‚ which can easily escape without interfering bodily functions Beta particles can destroy abnormal tissue.

8.01 Lab Report FLVS The purpose of this hands-on lab is to model the concept of half-life using a sample to represent radioactive atoms. Materials 200 M&M® candies‚ pennies‚ or other small candy/item with two distinct sides shoe box or other small box with a lid Procedure 1. Place 200 candies in the shoe box‚ lettered sides up. The candies will stand for atoms of a hypothetical radioactive element. 2. Cover the box and shake it vigorously for three seconds. This is one time interval.

Forgetting is the inability to recall or recognise information that was once stored in the memory and is now not available or cannot be accessed. There are four main theories to forgetting; trace decay‚ cue dependant‚ displacement and interference. Displacement seeks to explain forgetting in the short term memory. According to Shiffrin and Atkinson’s model of memory‚ the short term memory has certain characteristics such as limited capacity so if information is not rehearsed‚ it would be forgotten

Lesson 08.01: Half-life and Radioactive Decay · Distinguish between nuclear and chemical reactions. · Compare and contrast different types of nuclear decay and the properties of the three types of radiation (alpha‚ beta‚ and gamma) discussed in the lesson. · Be able to predict the isotope or radiation produced by a nuclear decay reaction when the other product is given. · Describe and make predictions regarding half-life‚ including using a graph or set of data to determine the half-life of

the town. The bizarre outcome is further emphasized throughout by the symbolism of the decaying house‚ which parallels Miss Emily ’s physical deterioration and demonstrates her ultimate mental disintegration. Emily ’s life‚ like the house which decays around her‚ suffers from lack of genuine love and care. The characteristics of Miss Emily ’s house‚ like her physical appearance‚ are brought about by years of neglect. For example‚ the house is located in what was once a prominent neighborhood

organisms‚ after eating the plant foods and getting carbon from atmosphere. At the time of death of the organism‚ as a result of decay‚ the amount of radioactive isotope decreases‚ which allows archaeologists to examine the age of excavations. • Radioactivity in many countries is also used for food preservation. The radiation destroys microorganisms and inhibits decay‚ which in consequence prevents poisoning and extends product shelf-life. Fixed irradiated food still has the essential nutrients

primary sources of radon gas? What elements are found when radon decays? How can this gas cause different kinds of diseases? OBJECTIVE: Build a simple ionization chamber that is capable of detecting fairly low levels of radiation BACKGROUND OF THE STUDY Radon is a cancer-causing gas. It comes from the natural breakdown of uranium in soil‚ rock and water and gets into the air you breathe. These radioactive materials "decay" into lighter elements‚ emitting energetic sub-atomic particles

Chris Pauley Ernest Rutherford was a New Zealand physicist and chemist who earned the title “Father of Nuclear Physics” after his discoveries of radioactive half-lives‚ differentiated between alpha and beta radiation‚ and proved that radioactivity involved the transmutation of one chemical element to another. He is also the recipient of the 1908 Nobel Prize in Chemistry "for his investigations into the disintegration of the elements‚ and the chemistry of radioactive substances". Ernest
