Bubble detectors are the most sensitive, accurate, neutron dosimeters available. Used for over 25 years by nuclear facilities, research institutes, military personnel, and the medical community, bubble detectors provide instant visible detection and measurement of neutron dose. Inside the detector, tiny droplets of superheated liquid are dispersed throughout a clear polymer. When a neutron strikes […]
The FNS-100 is a high efficiency, high resolution fast neutron spectrometer. The detector is a multi-wire 3He ion chamber with a dense quenching gas. The availability of both high efficiency and exceptional resolution in one instrument makes the FNS-100 useful for nuclear science and engineering, materials research and radiation protection. The FNS-100 is supplied with […]
ROSPEC is a user friendly, unique rotating neutron spectrometer designed specifically for the spectral measurement of degraded fission neutrons, which may be encountered in nuclear power and fuel processing plants, weapons-related military facilities and accelerator laboratories. Introduced in 1992, ROSPEC has a proven operational record with a program of continued performance upgrades. ROSPEC is intended […]
MICROSPEC calibration caps are used for automatic energy calibration in BTI’s MOBILE MICROSPEC and MICROSPEC-6 spectroscopic probe systems. An appropriate cap must be purchased separately for each probe purchased. These cal caps contain small amounts of Na-22 or Cd-109. Due to the small amounts of nuclear material present in these caps, their shipment are exempt […]
The Simple Scintillation Spectrometer (SSS) is a neutron spectrometer intended to complement the spectral range of BTI’s ROSPEC system, allowing measurements from 4 to 16 MeV. The SSS detector is an array of small plastic scintillators coupled to a photomultiplier tube. The dimensions of these scintillators are selected to optimize the neutron response functions of […]
BTI’s MICROSPEC systems were the first truly portable spectroscopic instruments providing the two essential pieces of information required by health physicists–dose rate and radionuclide identification. In addition to an extensive line of photon probes, BTI offers the only commercially available portable beta spectrometer, the B-Probe. Skin dose measurements using traditional thin-window Geiger-Mueller (GM) counters have […]
The MICROSPEC X-Ray Probe was developed to perform spectral and dose-equivalent measurements for low-energy photons for assessment of radiological hazards for the skin Hp(0.07) and eye Hp(3). The measurement of low-energy photons is often complicated by the presence of high-energy gamma rays that produce counts in the low-energy regions, which interferes with the counting of […]
Sodium iodide (NaI)-based detectors continue to be an excellent choice for field instruments, combining high efficiency and simplicity with good resolution at a reasonable cost. However, NaI basic response is a poor match to tissue response and its sensitivity varies dramatically with energy. Many NaI monitors merely use a discriminator above a particular gamma-ray energy […]
The MICROSPEC Neutron Probe (N-Probe) is a revolutionary portable neutron scintillation spectrometer, designed to be used by non-specialists for measurement of low-intensity neutron doses in the mixed field environments often found in nuclear utilities, fuel storage areas, fuel and waste processing operations and military applications. It is compatible with the current generation of MICROSPEC analyzers […]
The MOBILE MICROSPEC is a compact, spectroscopic mobile system that can be easily mounted on any vehicle platform. It can operate two MICROSPEC probes simultaneously, enabling the user to perform a combination of gamma, neutron, beta and/or X-ray spectroscopy using a single analyzer. MOBILE MICROSPEC comes in a rugged, splash and dust resistant enclosure that can […]
