What is radiation physics?

physics is a scientific study of matter and energy and their interaction. Energy, such as light, warmth or sound that is emitted from one source, travels through space or material and is then absorbed by another object, is defined as radiation. Radiation physics is a physics industry that studies the effects of radiation on matter. This field was helpful in providing improved production processes, nuclear energy and advanced medical diagnostic and therapeutic options. Alpha are particles containing two protons and two options that are emitted from the atom core. Betas are high -speed particles that seem identical to electrons. Neutrons are neutral particles in the core of all cells. Gamma rays are emitted by the core and X -rays are the result of changes in the core energy.

X -ray technology is one of the most familiar of the application of radiation physics and has several production applications. For example, the automotive industry uses high -ENE X -ray rays to evaluatergie. X -ray microscopes are used to inspect the stent and catheters during the production process and measuring the thickness of the X -ray beam measure the chemical composition of metal alloys. X -ray radiography is used by archaeologists to explore ancient artifacts.

The

oil industry used oil treatment and production. Oil companies use a radiation process called radiation thermal cracking (RTC) during oil production, heating oil, tar and processing of by -products of oil extraction. RTC has a higher production rate, lower costs and much lower energy consumption than tradition methods. Radiation treatment of oil contaminants provides greater environmental protein than other methods.

Nuclear energy is a growing field that is based on applied radiation physics. Through the process known as nuclear cleavage, energy is extracted from atoms during the controlled JADerneous reactions. While the United States produces the largest amount of nuclear energy, France produces the highest percentage of electrical supply to its nation through nuclear reactors.

The field that benefits most about radiation physics is medicine. Through the application of physics, scientists have developed methods of using ionizing radiation for the diagnosis and treatment of health conditions. This includes not only traditional forms of X -rays, but also ultrasonic, magnetic resonance (MRI) and nuclear medicine.

Most nuclear medicine includes displaying and employs computers, sensors and radioactive materials called radiopharmaceutics. The X -rays, the oldest form of depiction, uses the world of high -frequency rays of the world to design the image. Gamma rays have even higher frequencies and are used in nuclear display. Positron emission tomography (PET) and one -time emission computed tomography (SPECT) are two of the most widely used nuclear imagingon the device.

The most common use of radiation therapy is for the treatment of cancerous tumors. This usually involves storing X -rays with high energy in cancer cells. The radiation is absorbed by a cell, causing it to die. The radiation is generally supplied to the tumor through an external source. The challenge for medical physics is to direct radiation in such a way that the minimum number of healthy cells is destroyed.

radiation brachytherapy includes internal application of radiation materials. In this treatment, radioactive "seeds" are implanted near the tumor. The release of radiation is slow and the distance between the seeds and the tumor is sufficiently short, that exposure to radiation to healthy cells is limited.

Benefits radiation physics exceed several disciplines and industries. Concerns about the possible exhaustion of fossil fuels make the development of nuclear energy in many countries with a permanent priority. The nuclear medicine field explodes, and new tests and treatment are developing rapidly, making physics radiačDiscipline that will continue to grow.
