The medium penetrating power of beta particles provides a range of useful applications which include: thickness detectors for the quality control of thin materials i.e. paper. treatment of eye and bone cancers, strontium-90 or strontium-89 are commonly used.
What are some uses of beta radiation?
Uses of beta radiation
- Beta radiation is used for tracers and monitoring the thickness of materials.
- Doctors may use radioactive chemicals called tracers for medical imaging. …
- Radiation is used in industry in detectors that monitor and control the thickness of materials such as paper, plastic and aluminium.
How is beta radiation used in daily life?
Beta particles can be used to treat health conditions such as eye and bone cancer and are also used as tracers. Strontium-90 is the material most commonly used to produce beta particles. Beta particles are also used in quality control to test the thickness of an item, such as paper, coming through a system of rollers.
What is an example of beta radiation?
Examples of some pure beta emitters: strontium-90, carbon-14, tritium, and sulfur-35. Gamma radiation and x rays are highly penetrating electromagnetic radiation.
Where are beta particles used?
Beta particles are also used in some forms of therapy to kill cancer cells. In addition, the emission of beta particles is used indirectly in the medical scanning technique known as positron emission tomography (PET).
How is beta used in medical tracers?
Emitters of beta radiation or gamma radiation are used because these types of radiation readily pass out of the body, and they are less likely to be absorbed by cells than alpha radiation.
What are alpha beta and gamma rays used for?
Alpha radiation is the name for the emission of an alpha particle in fact an helium nuclei, beta radiation is the emission of electrons or positrons , and gamma radiation is the term used for the emission of energetic photons.
What type of radiation is used for sterilization?
Gamma irradiation Gamma irradiation is the most popular form of radiation sterilisation and is used when materials are sensitive to the high temperature of autoclaving but compatible with ionising radiation.
Is beta radiation used in medicine?
Beta-emitting radiopharmaceuticals are finding wider applications in cancer treatment, such as radioimmunotherapy and bone-seeking radiopharmaceutical therapy. Beta-emitting radioisotopes have also been extensively used in vascular brachytherapy and other brachytherapy applications.
Why is beta used in paper thickness?
A beta source is used because beta radiation can penetrate paper or thin aluminium, but the amount of penetrating will vary sufficiently as thickness changes. The source should have a long half-life so that the count rate remains almost constant each day and so that it does not need to be replaced too frequently.
