Welcome to brimRADTM
The brimRADTM Corporation is a newly formed company focused on the fabrication, production and delivery of next-generation, solid-state radiation detectors. brimRADTM is employing the use of mercurous halide materials, a transparent semiconductor crystal that has superior characteristics in terms of higher efficiency and substantially lower size and weight. The company also is exploring the use of a group of ternary wide bandgap semiconductors for radiation detection and imaging. The new company is a member of the Brimrose family, which has a 37-year history of innovation and technological knowhow. It is poised to deliver improved detection capabilities for the medical, security, defense, aerospace and industrial markets.

The brimRADTM Corporation is the inspiration of Dr. Ronald G. Rosemeier, founder of the Brimrose family of companies, and Dr. Sudhir Trivedi, the Director of R&D of Brimrose Technology Corporation (BTC). Together, they have generated more than $190 million in federal contracts for BTC, and have overseen the engineering of numerous products. Through his extensive work with advanced materials, Dr. Trivedi has developed a deep understanding of mercurous halides, which hold the potential to provide a better set of radiation detectors for a variety of applications. brimRADTM is incorporated and the name is trademarked.

The new company has the unique capability of being able to grow its own crystals, a compelling core advantage of the Brimrose companies for many years. This allows the company to design and engineer the detector crystal module to the specifications required for multifunctional, optical and electrical applications.

The large majority of the radiation detector market is supplied by 80-year old, scintillator-based technology presently used today. This slow and low efficiency technology continues to provide large, heavy and out-of-date, low-tech results. In recent years, a solid-state industry has begun to grow centered on cadmium-zinc-telluride (CZT) products. In typical Brimrose fashion, brimRADTM is changing the technology tide.

These advanced, high-efficiency detection systems hold the promise of delivering an entirely new generation of products housing radiation detectors, including radiation sensors for the security industry; radiation detectors for new, improved and potentially smaller medical imaging devices; and sensing devices for the industrial community.

The U.S. Air Force and NASA already have provided Phase I and Phase II SBIR awards for these mercurous halide materials totaling over $2M.

We are developing the radiation detectors that can improve NASA’s ability to determine the surface and subsurface composition of planetary bodies from orbiters and landers. Unlike most radiation detectors, these detectors can potentially perform both gamma and neutron spectroscopy. The new detectors are based on the mercurous halide materials.

For the U.S. Air Force, we are developing rugged, portable, low-cost and very-high-performance detectors from mercurous bromide (Hg2Br2) that can detect both gamma radiation and neutron particles in support of defense and security measures. The primary objective of the Phase II portion of the program is to develop a full-scale prototype, high performance, low cost, energy efficient and robust pager-form device, based on the novel mercurous bromide materials.
