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. 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 droplets provides a direct measurement of the tissue-equivalent neutron
dose.
The Bubble Detector is the only neutron dosimeter where
the response is independent of dose rate and energy, with zero sensitivity
to gamma radiation. Bubble Detectors are so compact, lightweight, and
rugged, that they can be clipped to a coat or shirt pocket, placed in
areas with limited access, or used in close proximity to a neutron source
for a quick assessment. With an isotropic angular response, neutron dose
can be accurately measured regardless of the direction of neutrons relative
to the detector. Bubble Detectors are ideal for ALARA programs, providing
the user with an immediate measurement of neutron hazards. |
