Title: Innovations of Joel E. Hegland in Radiation Dosimetry

Introduction

Joel E. Hegland is an accomplished inventor based in Pullman, WA (US). He has made significant contributions to the field of radiation dosimetry, holding two patents that showcase his innovative approach to measuring and managing radiation exposure.

Latest Patents

Hegland's latest patents include advancements in radiation dosimeters and dosimeter badges. The dosimeter badges consist of first and second parts that are securely connected to create a sealed area for holding and protecting at least one dosimeter. These badges are designed to allow for the exposure of dosimeters to a stimulating laser beam, which is used to read dose exposure information. The construction of the badge facilitates automated disassembly and reassembly, ensuring a uniquely fitting relationship. Additionally, an electronic memory is integrated to provide calibration and identification information during the reading process. Hegland's patents also introduce dosimeter mounts that reduce thermal heating requirements, along with methods for producing dosimeters using thin substrates and phosphor binder-layers.

Another notable patent is focused on remote radiation dosimetry. This invention discloses methods and apparatus for remotely measuring radiation levels, particularly useful in radiation therapy. The apparatus employs a beam generator, such as a laser beam, to stimulate a remote luminescent sensor mounted in a probe. This sensor emits stored luminescent energy resulting from exposure to ionizing radiation. The stimulating beam is communicated to the sensor via transmissive fiber, which also returns the emission from the sensor. The invention includes a beam splitter to create a detector beam, which is measured for power during the reading period, allowing for precise control of the beam generator.
