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 deflected by a sheet of paper. They show a small threat of hazard to the external bod and can cause serious damage if breathed in. The symbol for alpha radiation is “α”
Beta Particles
- Beta particles are all of the same size and depth as the electrons. Beta particle can have negative or positive electric charge and can travel at speeds as high as 99 % of the speed of light. Beta radiation can force through human skin and damage the tissue, but it can’t penetrate thin layers of plastic wood or aluminium. The symbol for Beta radiation is “β”
Gamma rays
- Gamma rays are not particles but are bursts of energy released after alpha or Beta particles are emitted. Gamma rays travel at the speed of light and

Radiation can cause a great deal of damage to living cells and the DNA inside a nucleus, and if the DNA becomes greatly damaged, that is when it becomes cancerous. Exposure to high amounts of radiation can significantly increase the risk of developing cancer. Alpha, beta and gamma radiation are the 3 different forms of radiation, and all are dangerous to humans and the environment. Although Alpha radiation cannot penetrate the skin, if a particle emitting alpha radiation is inhaled or eaten, it can do significant damage to the cells in internal organs. Beta and gamma radiation have strong enough wavelengths to penetrate the skin and damage cells inside the
Gamma: this is a ray of electric radiations this is a part of electromagnetic spectrum. In the high energy and low wave frequency part. When ionising gamma rays pass through gamma because they are weak, travel through space and vacuum.
Gamma radiation has 0 charges and 0 atomic mass and atomic number. It has a very high penetrating power than alpha and beta because it does not stop for many centimetres. The ionising power of gamma radiation is very low according to alpha and beta radiation. It is used to treat cancer and testing equipment; however it can be very dangerous for human health if it comes in contact with
When in the body, this type of radiation is even more
All kinds of ionizing radiation that used in health care centers in medical diagnosis and therapy processes, as well the radiation used in diagnostic radiology is the field of medicine that uses radiation to make an imaging exams and procedures to diagnose a patient. In another hand it’s used to treatment for many kind of disease especially to cure from cancer. In any form of medical care, diagnostic radiology plays a significant role in the diagnosis and treatment of disease or injury. The exams often use radiation, at many levels that have been determined and adjusted to be safe as possible, to create detailed anatomical images. (Bekas M, et al, 2016)
They usually cause something specific too. For example, ultraviolet radiation gives people sunburns (if exposed a sufficient amount). X-rays and gamma rays can make people sick or even die. If the dose is not sufficient, then there won’t be explicit effects (called non-ionizing radiation), however it is still dangerous.
To continue, gold has other uses in the medical field along with treating brain disorders. This is because gold is able to absorb radiation. Radioactivity occurs when unstable atomic nuclei decompose to form nuclei with a higher stability. Energy and particles are released during the decomposition process causes radiation. There are three different types of radiation; alpha, beta and gamma. Alpha radiation is when an alpha particle, or helium nucleus, decays into an atom with a mass number that is reduced by four and an atomic number that is reduced by two. Idaho State University (2011) explained that beta radiation is when an electron is released from the nucleus of a radioactive atom, along with a particle called an antineutrino (para.
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
The process where food is exposed from nuclear sources consists of food irradiation, which is limited to high-energy gamma rays, X-rays and accelerated electrons. Ionizing is source of radiation because of the high-energy free electrons from atoms and molecules. The electrically charged particles are converted to ions. Microwaves are example of gamma rays. Accelerated electrons can transfuse to treat the food only to a depth of three centimeters. Due to thickness of x-rays may pass through the food.
Radioactivity is when energy is emitted from the nucleus due to the nucleus being unstable. The 3 types of radiation are Alpha ,Beta and gamma. Alpha particles have 2 protons and two neutrons. Examples of radioactive nuclei that emit alpha radiation. Are : uranium, thorium, actinium, and radium They are very ionising so they give energy off onto whatever they are in contact with. Therefore, it loses energy more quickly. They are not very penetrating so can be stopped by a piece of paper or skin. Beta particles have 1
“When we speak of dangerous radiation exposure, are we speaking of alpha radiation, beta radiation, or gamma radiation?”
Radiation is one of the main forms of energy (Pettigrew 1). In today’s environment we are only familiar with the basic types of radiation. These types are in the form of
Also while he was there, he was invited by Professor J.J Thomason to study the conductivity of gases, resulting in a paper about dividing atoms and molecules into ions. This lead Rutherford on to taking a closer look at ion-producing radiations and he discovered that putting uranium near foil will result in one type of radiation being easily soaked up or blocked, while another type had no problem penetrating the same foil. Then, he labeled the two radiation types “alpha” and “beta.” He then found out that the alpha particle was the same as the nucleus of the helium atom, and the beta was the same as an electron or composition. He took a professorship at McGill University of Montreal and left Cambridge in 1902. In 1903, he and Fredrick Soddy introduced their disintegration theory of radioactivity, and it claimed that radioactive energy was emitted from within an atom and that when alpha and beta particles were emitted at the same time they caused a chemical change across elements. Rutherford and Bertam Borden Boltwood, continued to categorize radioactive elements into what they called a “decay series.” Rutherford was honored with discovering the radioactive gas radon while at McGill. He achieved fame for his contributions to understanding of radioelements, and published many magazine
Β-particles are high energy electrons which are ejected from the nucleus with a range of energies up to a maximal value.12 β-emitters are heavily researched and are a widely accessible form of radionuclide therapy. The LET of β-emitting particles is high enough to kill cancerous cells, but is considered low compared to α-emitters which have a lot more particles in the higher energy levels. Β-particle emitters deposit their energy over a much larger range (1mm, dependent on energies) compared to that of α-particles and Auger electrons.17 One benefit to this is that less work is needed on carrier molecules, as the distribution of the β- emitter is not as critical for the radionuclide therapy to be successful. β-emitters are the widest used and researched radionuclides as they offer a large range of energies, tissue penetration, half-lives and production methods.18 This means, depending on the type and size of the tumour, the radionuclide can be varied. For example for a large tumour, a β-emitter would be more effective than an α-emitter, as although it has a lower LET, the whole tumour can be targeted rather than a small area. Nuclear reactors are the most common mode of producing β-emitting radionuclides, however charged particle accelerators can also be used. The wide range of radionuclides has in itself become a problem as it often becomes hard to select the most appropriate. Some of the primary β-emitting radionuclides that are
Beta Radiation is a high-energy electron that carries a negative charge. That is send out by some radioactive nuclei. And it is ionizing than Alpha radiation and more ionizing than gamma rays. This makes travel through many centimeters or even meters. And millimeters through the skin and tissue.
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.
