Final answer:
Beta particles have unique uses in tracer studies, smoke detectors, and CT scanners.
Step-by-step explanation:
Beta particles can be used in tracer studies to trace the movement of chemicals in the environment. By labeling the chemicals with radioactive beta-emitting isotopes, scientists can track their path and determine their behavior. This technique has applications in environmental science, agriculture, and environmental remediation.
Smoke detectors also utilize beta particles. In a typical smoke detector, a small amount of radioactive material containing a beta-emitting isotope is present. When smoke enters the detector, it interrupts the flow of beta particles, triggering the alarm.
Although not unique to beta particles, CT scanners also make use of them. CT scans use X-rays to capture images of the body, and beta particles can be produced as a result of the interaction between the X-rays and the body's tissues.
