Task 1.2- Properties ( Part Of P1 )

Alpha radiation occurs when there are most neutrons in an atom, which causes the atom to turn into an isotope. Alpha radiation is formed due to the atom not being able to sustain the extra neutrons in the nucleus. The atom undergoes radioactive decay, which will emit helium particles (alpha radiation) which consists of two protons and two neutrons in order to stabilize itself.

This is a report which has been created to introduce new childcare practitioners to safeguarding within a childcare setting. This will help new practitioners to understand current legislations within the United Kingdom.

High doses of radiation kill cancer cells and stop them from spreading, while at low doses radiation is used to see insides of the human body, such as x-rays (WebMD).

I am confident that my creativity, communication, and organization skills will benefit Towson’s residential community. Being creative breaks monotony and can make things interesting for everyone involved. Communications skills are important to have for this position since I will be working with residents and other RAs on a daily basis. Having transferred from two other schools, I have met many people and experienced many different things, which I believe makes me more relatable than just your average person. Being organized and detail-oriented makes working with me simple and reduces stress for everyone. Due to my positive and empathetic personality, I am an easy person to talk to and get along with.

Danny Goldberg argues in "The Government Should Not Restrict Media Marketed to Children” that FTC regulation on media is affecting the entertainment industry’s profits on production of violent media content. The specific bill introduced is the Media Marketing Accountability Act of 2001. He believes that there should not be a restriction placed on marketing media to children. Goldberg posits that FTC regulation is a “radical bill” that takes away the power of parents to determine what is appropriate for their children (Goldberg). An additional point the author makes is that many of the restricted media, specifically rap music, is produced by African Americans; therefore, there is a culture bias on these restrictions. Thirdly, Goldberg states that limiting marketing on media to children, specifically

After discovering the reading of four writers on slavery, I have learned new and exciting information about the institution of slavery. Throughout this paper I intend to inform you of there thoughts and actions and how I perceived them. I also intend to analyze how the lifestyle and upbringing of these writers affected their writing. Being able to uncover what these readings mean has been both challenging and rewarding.

Its gamma ray energy of about 140 keV is convenient for detection. The fact that both its physical half-life and its biological half-life are very short leads to very fast clearing from the body after an imaging process. The help that the scan provides using technetium 99m easily out ways the risks in its use. Technetium 99m is inserted into the body through an injection or iv (inter-vascular). It then breaks up in the body via gamma radiation, it builds up where there is an increased flow in blood which indicates a disease. Or in areas of abnormality. This build up is detected by a gamma camera and then a scan is produced imaging a physical image ready to be examined or viewed. Some specific benefits include low gamma radiation, short half-life (approximately 6 hours), a minute harm to the body, and the ease and flow in the time it takes to pass through the body. Overuse of this radioisotope could lead to cancer or other abnormalities to the brain or

Medalia (2011) concludes that ionizing radiation, in other words radiation separate from harmless radio waves and light, has the ability to knock electrons out of atoms, causing a condition that produces an electrically charged atom that can damage human cells. Only a very small amount is needed to produce biological change. Symptoms include cancer, genetic mutations, sickness, vomiting, diarrhea, hemorrhaging, and at high doses, death within hours (Medalia 2011).

1.4) Do some online research to find information on several businesses that have benefited from implementing unified communications. Write a short paper describing how/why they are using unified communications and the business benefits that they have realized ?

The Beta travels faster and penetrates further than any other. Gamma rays are the most dangerous from all since the can travel further and damage tissues and organs. Radiation can be measured in doses such as the Roentgens and the Rem. Radiation in our planet can come from cosmic radiation, terrestrial sources, the body, or man-made sources such as diagnostic radiology and therapeutic radiology. When a person is exposed to radiation he/she can suffer from acute effects also known as effects that occur quickly or chronic effects which are known as long term effects. People can handle chronic exposure to radiation better than a large amount of radiation within a short period of time. People who have a been exposed to large amounts of radiation within a short period of time can become ill quickly such as in acute radiation sickness or could potentially die from such exposure. Exposure to radiation can cause illnesses such as cancer, cataracts, and could ultimately cause a reduction in life. America uses emergency managers to handle aspect of all emergencies posed to communities across the country. Emergency managers use The Radiological Protection System trains and aids communities when radiological emergencies occur. In the United

In 1899 Rutherford discovered radioactivity as well as alpha, beta and gamma rays, these were found while he was performing studies on the absorption of radioactivity, which was done by using thin sheets of metal and two components that he found, alpha and beta. Alpha radiation is absorbed by a centimetre of a few thousandths of metal foil. Beta radiation can progress through 100 times as much foil before it will be absorbed. While Rutherford found the two rays he yet found another shortly after called the gamma ray which can puncture as much as several centimetres of lead.

People can differentiate between different types of radiation by finding the source of radiation, the amount of energy being carried, and any particles involved.

X-Ray and Gamma radiation are the heart of this therapy. Either produced through the beta decay of Cobalt-60 or a linear accelerator, external beam radiation delivers a beam of high-energy x-rays to a patient’s tumor site in order to destroy the cancer cells. In most cases, patients receive therapy in daily treatment sessions over the course of several weeks. Many types of external-beam radiation therapy are delivered using a linear accelerator. The Linac uses direct current or radio frequency voltages accelerating electrons through then length of a waveguide, a hollow tube vacuum chamber, to a velocity near the speed of light. When the electron reaches the end of the acceleration tube, it smashes into a metal target, usually tungsten or aluminum. This collision creates the high-energy radiation used to treat cancer. Depending on the metal target used for the final collision, different radiation is generated for specific treatments3.

radiation) or it can be put inside needles, seeds or catheters and placed inside your body near the cancer

IIR filters are digital filters with infinite impulse response. They have the feedback (a recursive part of a filter) and are known as recursive digital filters. They are the time invariant systems. IIR filter has better frequency response than FIR filters.
