a nucleus decays, particles and energy are emitted from it. We call this emission nuclear radiation. Three types of nuclear radiation are alpha, beta, and gamma radiation. Alpha and beta are composed of particles. Gamma radiation is composed of electromagnetic waves.” (Mc-Graw Hill Physical Science p.621.) Alpha decay is a radioactive process in which an alpha particle particle with two neutrons and two protons is removed from the nucleus of a radioactive atom. The alpha particle is basically identical

an unstable atom in the form of particles and wave. All matter is composed of atoms, which are the smallest part of an element that retains the characteristics of that element. The atom consists of two parts, the nucleus of the atom and the electron shell. Within the nucleus there are positively charged particles called protons and neutral particles which are called neutrons. Orbiting around the nucleus (electron shell) of the atom are negatively charged particles called electrons. If the number

all matter. There are 3 different type of ionizing radiation. Alpha, Beta and Gamma. An Alpha particle consists of 2 protons and 2 neutrons bound together into a particle identical to a helium nucleus. This is the least powerful radioactive particle. Alpha particles cannot penetrate the human body at all. They do not affect the human body unless they are consumed. Beta particles are high energy, high speed electrons. The beta particles emitted are a form of ionizing radiation also known as beta rays

emit alpha radiation, a highly hazardous type which is also emitted by Uranium. It has been concluded that plutonium has a higher radioactivity, hence a faster half-life. What is Radiation? Radiation is excess energy, which travels through space in the form of heat, light, sound, microwaves, radio waves and x-rays. Low radioactive substances can be found everywhere. When much more sophisticated elements are subject to decay, they release many types of radiation; the most common are alpha particles

Nuclear energy has, for some time, been a controversial issue. With incidents like that of Chernobyl, Three Mile Island, and the more recent complications caused by the earthquake and tsunami Fukushima reactors in Japan, concern about the safety of nuclear energy has become a major issue. A lot of this concern probably exists because of a lack of information and education about both radiation and its effects. It is my belief that nuclear power is no less safe than any other form of energy generation

positive charge whilst neutrons are neutrally charged. When the ratio between these sub atomic particles is too large or too small, the nucleus becomes unstable. The ratio between neutrons and protons in this isotope is too large, making the nucleus unstable and therefor radioactive. The ratio is too large due to their being 2 more neutrons to protons. This results in the isotope emitting a beta particle, causing Carbon-14 to be converted into nitrogen-14. On this earth, there are 3 naturally occurring

stability (1:1.3 – 1:1.5). Alpha: Ionizing radiation emitted by some substances undergoing radioactive decay. It is in fact a helium nucleus with a +2 charge. It is formed when the ratio of neutrons to protons in the nucleus is too low which causes the element to be in an unstable energy state. Alpha radiation is unable to penetrate paper as shown in the diagram. Despite their inability to cause damage from outside the body, if ingested they are able to ionise the particles within the body as it has

Radioactivity is the energy or particles that are released from the nucleus of an atom due to spontaneous changes. Some atoms are unstable, and emitting radiation will achieve a stable state. The main forms of radiation emissions from a decaying and unstable nucleus can be in the form of alpha, beta or gamma radiation. When a positively-charged particle is emitted from the nucleus of an atom, this is called alpha decay. This alpha particle would consist of two protons and two neutrons, similar to

at McGill university, Rutherford was rewarded the nobel prize for chemistry. In 1907 he succeded Arthur Schuster at the University of Manchester. He began persuing alpha particles in 1908. With the help of Geiger he found the number of alpha particles emitted per second by a gram of radium. He was also able to confirm that alpha particles cause a faint but discrete flash when striking luminescent zinc sulfide screen. These great accomplishments are all overshadowed by Rutherford's famous Gold Foil

nucleus splits into two smaller nuclei. 3. Alpha, Beta, and Gamma radiation is produced when an unstable nucleus decays. Alpha particles are made of 2 protons and 2 neutrons. This means that they have a charge of +2, and a mass of 4 Alpha particles are relatively slow and heavy. They have a low penetrating power - you can stop them with just a sheet of paper. Because they have a large charge, alpha particles ionise other atoms strongly. Beta particles have a charge of minus 1, and a mass of
