Exactly, today, I'm playing around with a laptop in the room a friend. Precisely in North Sumatra University Dormitory Son. In the beginning, with good intentions we want to do basic electronic journals for the title of a transistor amplifier with an analysis of the parameters h. However, it is called the devil is always there, so our idea is not to be working on the journal and did not even enter the lab to lab.
It occurred in my heart to think what useful thing I can do. My friend (his name just info Ahmad Muhajir) was doing at the time of reinstalling it. I myself have just completed the midterm, and silently stared at the stake was fiddling with his favorite notebook. Ah, finally a short story I had glanced at his core physics lab journal, and I made the material in my blog, Next, I typed his nuclear physics lab journal and write it as an article in my blog. Simply, do not need much introduction, starting with the title as follows
GM tube characteristics and Dead Time Counter
Experiment objectives:
1. To determine the characteristics of Geiger-Muller counter
2. To know the meaning of the Dead Time Counter
3. To determine the radiation emitted by radioactive materials used in the experiments
4. To know the meaning of the plateau region and its connection with Geiger-Muller counter
As the number mass that becomes larger, the comparison between neutrons and protons in a nucleus becomes larger for a stable nucleus. Possibility of unstable nuclei have a neutron excess or deficiency and experienced a transformation process known as beta disintegration. Unstable nuclei can have a variety of other processes such as alpha disintegration or disintegration neutrons.
As a result of the disintegration-shedding, the core end is in a more stable or have a stronger bond configuration.
In 1896, a physicist from France named Henry Becquerel discovered that crystals of solid uranium-rays emitted rays similar to X-rays with high penetration rate, which can lead to a photographic plate, and induce conductivity electricity in gases. Becquerel is accompanied by findings identified two other radioactive elements in 1898, namely Plutonium and Radium, by a husband and wife that Pierre and Marie Curie.
Heavy elements like uranium and thorium, and decay of an unstable and a chain from initial state radiation emitting elements.
Alpha decay. Alpha decay is the emission of alpha particles (helium nuclei) which can be represented as a Helium atom. When an unstable nucleus that issuing an alpha particle, the atomic number decreases by 2 and the masses derived by 2 anyway. The occurrence of a combination of kinetic energy from the core of the child (Thorium 230) and alpha particles are usually shown as TO. The amount of the TO and the gamma energy is equal to the mass difference between the original nucleus (Uranium 234) and the particle is proportional to the end because the binding energy released. Alpha particles will carry as many as 89 percent of the kinetic energy is, in many cases, which can be thought of carrying all the kinetic energy.
Beta decay. Beta decay is the emission from the core electron orbitals more than the original. These particles are released by the core electrons are excited and having a same charge sign. If both the energy and momentum is conserved, a third type of particles, neutrinos, v, must be involved. Neutrinos are associated with positive inter-particle electron emission. For all of the content of the particles, they all penetrate the material with a little, where the energies have not restore the initial state. Electron emission, which is represented as a simple electron or minus e is usually written, effectively converts a neutron into a proton, thereby increasing the atomic number by one and leave the mass number which is not charged. This is a common form of decay of a nucleus with a neutron excess.

Gamma decay. Gamma radiation is an electromagnetic energy radiation is very high and there is at the core. Nuclei emitted in the form of photons, separate files rather than the energy possessed by both wave and particle properties. Often a child's core left in a state of excitation after the ground state by emission of a gamma ray radiation. However, in some cases gamma rays (photons) collected from the core-core interaction only with one of the deepest of the electron orbitals, and as a result, the energy of the photons is transferred to the electrons. Gamma rays that have been mentioned experiencing internal changes. Conversion electrons are removed from the atom with kinetic energy equal to the gamma energy minus the binding energy of the electron orbitals. An orbital electron then falls into a state which is lower in energy states to fill the void, and this is an amalgamation of the characteristic X-ray emission.
