Radiation dosimeters are devices used to measure exposure to ionizing radiation such as, X-rays, alpha and beta particles, and gamma rays. The damage that this radiation can cause to a material (e.g., human tissue) is typically cumulative, related to the total ionizing dose received. Therefore, workers who are exposed to ionizing radiation are usually...

Before converting detected power levels to the digital domain, conventional antenna tuning systems couple incident and reflected powers through a three-line directional coupler in addition to two RF power detectors. Replacing these conventional antenna tuning systems with the automatic antenna matching techniques and devices employed at lower radio...
