Non-ionizing radiation is the term given to radiation that has insufficient energy to cause ionization. Doctors may use radioactive chemicals called tracers for medical imaging. X-Ray, CT, and PET machines use X-ray (X-ray and CT) and Gamma radiation (PET) to produce detailed images of the human body, which provide valuable diagnostic information for doctors and their patients. These kinds of radiations contradict with ionizing radiation like x-rays, gamma rays, and alpha particles, which are on the other end of the spectrum and are unstable and reactive. If alpha particles were used all of them would be absorbed and none would get through. Beta radiation is used for tracers and monitoring the thickness of materials. UV light(Ultra Violet light) has a lower penetrating power and a higher wavelength compared to X-rays and gamma rays, but it is used in the treatment of water or water purification and other hospital instruments and objects used in surgery or in the sterilization of drugs or laboratory hardware. At the source of the leak the intensity of the beta radiations will be high as no energy is lost to the pipe wall. Bone cancer is also treated by using beta tracers or concentrating high energy electrons to the affected part. Gamma radiation is used in the treatment of cancer, testing equipment and sterilising medical instruments. In paper mills, the thickness of the paper can be controlled by measuring how much beta radiation passes through the paper to a Geiger counter. Either a thick or thin product absorbs a different amount of beta radiation. The energy of beta particles varies markedly: it is very small for tritium and sulfur, but quite large in the case of, for example, phosphorus and sodium. These β particles can be used to treat health problems such as cancer of the eyes and bones and are also used as markers. Radiation detectors placed outside the body detect the radiation emitted and, with the aid of computers, build up an image of the inside of the body. There is another alternative method that can be used instead of beta rays. Uses of beta radiation. Other rays cannot be used because they can cause damage to other tissues. Beta-particles, being less ionising than alpha-particles, can travel though many centimetres or even metres or air and though millimetres of skin or tissue. Beta particles are high-energy, high-speed electrons or positrons emitted by certain fission fragments or by certain primordial radioactive nuclei such as potassium-40. Additionally, they are used in other forms of therapy to get rid of cancer cells. The radiation works by killing bacteria and viruses, or eliminating their ability to reproduce by severely damaging their DNA or RNA. Beta Radiation. Radioactive americium releases alpha radiation, which ionises the air inside the detector. Scientists, although only having known about radiation in the 1890s, have developed a wide variety of uses for this natural energy. Within radiology, we find more specialized areas like mammography, computerized tomography (CT), and nuclear medicine (the specialty where radioactive material is usually injected into the patient). Smoke from a fire absorbs alpha radiation, altering the ionisation and triggering the alarm. In paper mills, the thickness of the paper can be controlled by measuring how much beta radiation passes through the paper to a Geiger counter. In general, a sheet of aluminum a few millimetres thick will stop beta radiation. Beta-plus (β +) radiation is the emission of positrons, which are the antimatter form of electrons. Besides making plants stronger, radiation can be used to control insect populations, thereby decreasing the use of dangerous pesticides. You can’t breath in ‘radiation’. The most well known is using x rays to see whether bones are broken. Other uses of radiation Smoke alarms. Electricity- Radiation also helped in producing electricity through nuclear plants, 16 % of the worlds electricity is produced in nuclear plants, and in the US 109 nuclear plants contributes 22 % of the power grid. However, it can still be stopped by a small amount of shielding, such as a sheet of plastic. Medical Diagnostics- Radiation plays a big role in the medical field from X-rays, MRI's, and raidioactive traces. In addition to treating cancer, radiation oncologists may also use ionizing radiation to treat benign tumors that are unable to be removed by surgery. Use of protective clothing, coupled with good personal hygiene and decontamination, affords protection against alpha and beta radiation. It also is used to treat other health conditions like eye problems. Emitters of beta radiation. Beta radiation is used to treat eye and bone cancer.
