Bubble Detector Products

Bubble Detector Products

Bubble detectors are the most sensitive, accurate, neutron dosimeters available. Used for over 25 years by nuclear facilities, research institutes, military personnel, astronauts, 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 a droplet, the droplet immediately vaporizes, forming a visible gas bubble trapped in the gel. The number of bubbles provides a direct measurement of the tissue-equivalent neutron dose. Please select a product below or contact us for more information.

BD-PND – Personal Neutron Dosimeter

Bubble Detectors are the most sensitive, accurate, neutron dosimeters available. Used for over 15 years by nuclear facilities, research institutes, military personnel, and the medical community, Bubble Detectors provide instant visible detection and measurement of neutron dose. The BD-PND is the recommended detector for personal neutron dosimetry.

BDT – Bubble Detector Thermal

The Bubble Detector is the only neutron dosimeter where the response is independent of dose rate and energy, with zero sensitivity to gamma radiation. Health physicists and others who are especially concerned with thermal neutron dose can take advantage of the simplicity and low cost of thermal Bubble Detectors. The BDT Bubble Detector is preferentially sensitive to thermalized neutrons, with an exclusion ratio of thermal-to-fast neutron response exceeding 10:1.

RC-18 – Recompression Chamber for BDS

To recompress (re-zero) the bubbles in the BDS after an exposure, a hydrostatic pressure chamber is available.  18 BDS, in a plastic holder, are placed in the RC-18 and the chamber is filled with water.  Pressure is applied safely and easily with a screw down piston assembly.  18 BDS can be recompressed at one time in the RC-18, with recompression time in the order of 30 minutes.

BDR-III Calibration Detector

The BDR-III provides bar code-ready, fully automated counting with machine vision technology that generates database compatible files in a compact, simple-to-use instrument. To allow the user to verify the proper operation of the BDR-III, a calibration detector is provided with each reader. Additional calibration detectors can be purchased separately for the BDR-III reader as required.
