luminosity, atypical soft and bright X-ray afterglow, and the detection of a substantial thermal X-ray and optical component during the first day of emission. The early observations in the optical-UV and X-ray can help facilitate an in-depth study of both the thermal and non-thermal components of GRB 060218 and their relation to SN 2006aj. GRB 060218 was detected with the BAT on-board $ extit{Swift}$ on February 2006 18.149 UT. $ extit{Swift}$ slewed autonomously to the burst. This GRB had a very long T$_{90}$

Gamma rays are the most interesting wave in the electromagnetic spectrum. In 1900, Paul Villard discovered Gamma rays unexpectedly while he was conducting a radioactivity experiment (ARPANSA). He differentiated gamma rays from x-rays because he realized that gamma rays had a greater penetration power depth through his further study and research (ARPANSA). Gamma radiation studies revealed that they are very dangerous, but scientist also found a way to protect against gamma radiation and many beneficial

There are three different types of radiation, alpha radiation, beta radiation and gamma radiation all which can, in general terms can benefit human by usage in medical procedures to detect errors in the human body. However these radiation can also be the cause of defects and errors in the human anatomy. Alpha particles - Alpha particles are helium nuclei that contains two protons and two neutrons. Alpha particles are positively charged. They can’t travel easily through thin materials and can be

Science in the Media: Revolution Jessica Bradley NBC’s show, Revolution explores what life might be like almost 20 years after a worldwide blackout hits North America. The blackout in Revolution was an “artificially-caused apocalyptic event occurring in September 2012” (Revolution, 2014.) This event disabled all electricity. The blackout was originally a combat test on the Taliban, but a malfunction of Nanites caused a worldwide loss of power. 15 years later, power becomes briefly restored by the

Conclusion Abstract This paper goes over radiation safety precautions and all the health risk dealing with radiation. I will discuss the discovery of radiation, non-iodizing and iodizing radiation, natural exposure to radiation, Alpha, Beta, and Gamma radiation and how they affect us. Also the paper will be going over radiation from human activities: underground miners, radiologists, medical

1. * Ultrasound techniques are used to detect structure inside the body. A gel is used when a 1MHz transducer is placed on the skin to avoid acoustic mismatch at the skin-transducer interface. (a) Define acoustic mismatch (in this particular case). Acoustic mismatch, by definition, is the discrepancy between the acoustic impedances of two or more mediums (MacLennan, 2006). This occurs when a propagated soundwave, passing through one medium, travels into another medium of unequal impedance. In the

Nuclear medicine refers to the use of radioactivity to diagnose and treat diseases. Nuclear medicine is a rapidly expanding branch of chemistry that uses short-lived radioisotopes to seek out specific organs. Nuclear medicine can detect radiation coming from inside a patient’s body and as a result nuclear medicine can determine the cause of the medical problems based on organ’s function. The use of nuclear medicine techniques have increased due to its’ use of biological chemistry to target specific

Introduction It is difficult to determine the birth of nuclear medicine due to the many contributions made my scientists of carious fields. However, most notably, during bla blah Understanding the uses, benefits and side effect of nuclear medicine is crucial due to its significant and ongoing contribution to the medical field. Throughout this paper focus will be placed on how radioactivity has benefited the detection, control and at times, complete elimination of cancer. Background Nuclear medicine

Introduction: Humankind in the modern world is strife with daily battles ranging from treating cancerous tumours to finding out if oil is flowing in a trans-siberian oil pipeline. Radioisotopes seem to hold a solution to these and many more serious and challenging issues. Global Issue: Being able to survive is the key to the existence of the Human race. In our endeavour to survive, we now need to tackle Cancer; the untamed monster of the modern era. Radioisotopes can be crucial to this survival.

to radiation, such as using gamma rays for sterilization. There have been many controversies about food irradiation. Some people say that using nuclear technology on food can cause harm to the body. But I believe that using nuclear technology is the best way to remove any diseases on food to cause less harm to the human body. Irradiation can also be used to preserve nutrients in food and kill microbes that destroy them. Using preservation procedures exposes food to gamma radiation, a high-energy light
