uses of alpha radiation

Scintillation counters can be used to detect alpha, beta, gamma radiation. Beta radiation consists of electrons. Radiation exposure can be expressed in certain units. The truth is there are many uses for radiation that are safe and beneficial outside of generating power or blowing stuff up with bombs. Hence, an alpha particle is identical to the nucleus of a helium atom, … Doses of radiation. Smoke detectors make use of the ionising properties of alpha particles. Alpha radiation is used in the hospital to treat various forms of cancer through a process called radiotherapy. In light of the nuclear tragedy in Japan, here are my top 10 uses for radiation that are not making electricity or blowing stuff up. They can be used also for detection of neutrons. The thicker the substance the more the radiation is absorbed. Many smoke detectors use americium-241, an alpha particle emitter, to detect smoke. They also inhibit germination and premature ripening in fruits and vegetables. The radioisotope Colbalt-60 is used as the source for gamma rays. Amercium-241 has a half life of 432 years and is a good source of alpha … Alpha-emitting materials can be harmful to humans if the materials are inhaled, swallowed, or absorbed through open wounds. Alpha particles are commonly emitted by all of the heavy radioactive nuclei occuring in the nature (uranium, thorium or radium), as well as the transuranic elements (neptunium, plutonium or americium).. The smoke detector uses a tiny bit of radioactive americium-241, a source of alpha radiation. An air-filled space between two electrodes creates a chamber that permits a small, constant current to flow between the electrodes. Ionisation is useful for smoke detectors. Alpha radiation can be stopped completely by a sheet of paper or by the thin surface layer of our skin (epidermis). Alpha particles pose no direct or external radiation threat; however, they can pose a serious health threat if ingested or inhaled., beta particles beta particleA form of particulate ionizing radiation made up of small, fast-moving particles. Smoke from a fire absorbs alpha radiation altering the ionisation and triggering the alarm. The eye is a very delicate part of the body, and that why lo energy electric rays are used in treatment. Alpha particles are emitted from here, which ionise the air, so that the air conducts electricity and a small current flows. In nuclear reactors they are produced for example in the fuel (alpha decay of heavy nuclei). The most well known is using x rays to see whether bones are broken. Alpha radiation: Alpha radiation consists of two protons and two neutrons; since they have no electrons, they carry a positive charge. This decay occurs through emission of different particles. Alpha Radiation is unique when compared to other types of Brachytherapy, where sealed radiation seeds or micro capsules are placed inside or next to the tumor emitting Beta or Gamma Radiation. Alpha (α) radiation is just an alpha particle, consisting of 2 protons and 2 neutrons. Uses of alpha radiation. Other types, such as x-rays, can occur naturally or be machine-produced. Uses of Ionizing Radiation. or gamma radiation. Beta Particles. Medical Uses. The absorbed dose is the amount of energy deposited per unit of mass. There are many uses of radiation in medicine. Therefore, they have a mass of approximately , where .So, the mass of an alpha particle is 6.64×10-27 kg = 3.73 GeV/c 2.; Electrons and Positrons, which make up beta particles, are antiparticles of each other. An alpha-particle is identical to the nucleus of a normal (atomic mass four) helium atom i.e. They are used as smoke detectors. a doubly ionised helium atom. Emitters of beta radiation. It is also a byproduct of nuclear power generation. Due to their size and charge, alpha particles are barely able to penetrate skin and can be stopped completely by a sheet of paper.
