The Team

Radiation Detection Technologies, Inc. (RDT) was founded in 2011 out of the Kansas State University SMART Lab located in Manhattan, Kansas. Our company focuses on manufacturing quality radiation detectors and detector readout-electronic technologies for use in multiple industries including healthcare, defense and energy.

RDT began its enterprise by focusing on the neutron detection industry.  Given the exhaustion of 3He – a major component of traditional radiation detection – RDT has started commercializing micro-structured semiconductor neutron detectors (MSNDs) in order to replace traditional 3He-based radiation detection technologies. As we look forward, RDT will add new products that fit the replacement of traditional radiation-detection technologies as the 3He shortage continues to rise.
Due to the clarity of vision and passion of commitment that our founders and staff bring to the field of radiation detection, we believe RDT will be able to help solve radiation detection problems and improve traditional technologies in the radiation detection industry.  In fact, our micro-structured neutron detector technology has resulted in over 33 publications, four allowed patents, and an R&D 100 award for 2009 and 2014!

Electrical Engineer

Logan Whitmore is RDT’s Head Electrical Engineer and Chief of Security. He was first introduced to RDT while working as an intern at the KSU Electronics Design Lab. Which provides researchers with access to advanced electronics and assists with integrating electronics technology into research programs. Logan’s exemplary work as an intern earned him the responsibility of designing electronic systems, including electronics used by both RDT and CERN. His involvement on an award winning project caught RDT’s attention, and they hired him immediately after his graduation. As an undergrad at Kansas State University, Logan was in several extracurricular clubs and held leadership positions in two of them. He was the Safety Officer for the Electronics Design Club and the President of the KSU Makerspace. Logan’s love for science fiction fueled his inventive nature.
One of his personal projects was a replica of a Pipboy 3000 from the popular videogame series Fallout. This wrist-mounted computer not only included visual replicas of in-game screens, but also functioned as an oscilloscope and FM radio. Another personal project was a homemade universal TV remote made to resemble a Sonic Screwdriver from Dr. Who, a hit British TV show. Logan also worked collaboratively with students of varying fields. This included the development of an XY plotter attached to an EEG (brain wave tracker). This was for use by an artist in their work on developing different mediums for creating art. Outside of work, Logan enjoys video games, motorcycles, and traveling to conventions. He meets with different groups for D&D, and even acts as RDT’s DM.
