Radiotracer
Radiotracer is a radioactive substance that is used to trace and measure various processes in space and astronautical engineering. Radiotracers are used in a variety of applications such as studying the behavior of fluids in microgravity, monitoring the performance of spacecraft components, and detecting leaks in spacecraft fuel systems. Radiotracers work by emitting radiation that can be detected and measured by instruments, allowing engineers and scientists to track the movement and behavior of the tracer. The use of radiotracers is an important tool in space and astronautical engineering as it allows for non-invasive and accurate measurements of various processes in space.
