Bubble Technology Industries
The BD-PND is the recommended detector for personal neutron
dosimetry. Its
sensitivity exceeds the ICRP-60 requirements for neutron dosimetry.
It incorporates automatic compensation for sensitivity change
with temperature over the operational range of 20 – 37 deg C.
Nuclear laboratories, utilities and military personnel have
found that the BD-PND’s immediate visual response and high
sensitivity, coupled with its small size, light weight and rugged
construction make it the ideas device for ALARA programs.
Bubble Detectors are ideal for rapid and accurate measurements in a
broad range of applications:
· Nuclear power stations and nuclear research laboratories (neutron
dosimetry and shielding verification
· Hospitals
involved
in radiation therapy / nuclear diagnostics (neutron dosimetry and
LINAC shielding verification)
· Airline crew dosimetry and space applications (high altitude neutron
dosimetry)
· Military personnel (neutron dosimetry and hazard detection)
Minimum Order: 2
Your desired Sensitivity ( 0.33 - 33 bubbles per bub/mrem)
must be specified at time of
order.
BDT
The BDT Bubble Detector is preferentially
sensitive to thermalized neutrons, with an exclusion ration of
thermal-to-fast neutron response exceeding 10:1.
BDS - Bubble Detector Spectrometer
The
BDS (Bubble Detector Spectrometer) is based on specially formulated
bubble detectors that have different neutron energy thresholds.
Similar to fast-neutron activation detectors, the measured spectrum
from the BDS is derived by “unfolding” the response of the different
detectors of the BDS. Each spectral measurement is made with 36
detectors (6 of each threshold supplied – 10, 100, 600, 1000, 2500,
10000 keV). It has two very important properties – it is completely
insensitive to gamma rays allowing it to be used in areas with
intense gamma background and since it is passive, it can be used in
pulsed radiation fields. The BDS should be used whenever one wants
to know something about the energy of the neutron field, especially
where the neutron field is only a very small fraction of the total
radiation field. The BDS has been used to determine the neutron
spectrum in space and is often used in connection with pulsed
reactor operations and for assessing the neutron field from medical
(or research) accelerators. Detectors can be re-used through
recompression in a pressure chamber (available separately from
Pulcir, Incorporated).
RC-18
The RC-18 recompression chamber re-zeros up to 18 Bubble Detectors at a time in approximately 30 minutes.
BDR-III - Automatic
Bubble Reader
The
BDR-III is an affordable solution for automatic counting of large
numbers of detectors.
The BDR-III provides barcode-ready, fully automated counting with
machine vision technology that generates database compatible files
in a compact, simple-to-use instrument.
Mobile Microspec
Bubble
Technology Industries has developed a spectroscopic mobile system
that can be easily mounted on any vehicle platform. This system
(called the “MOBILE MICROSPEC”) is ideally suited for pilot
based/UAV air and driver based/ROV land platforms. MOBILE MICROSPEC
is perfect for rapid and accurate detection of gamma and
neutron-emitting materials by a broad range of users (Customs
officials; Cargo inspectors; Dock, airline and railway workers;
Military personnel; Police, firefighters and EMS personnel; and
Radiation monitoring authorities).
MOBILE MICROSPEC comes in a rugged, waterproof enclosure that can be
easily transported. A hard shell case can be supplied as an option
for external use with land vehicles, watercraft or aircraft. A
ruggedized laptop provides the user with real-time, straight-forward
information on the amount of radiation, the identity of the
radioisotope and the alarm status. The system conveniently operates
from a wide variety of power supplies, including: a built-in
rechargeable battery, any external 12 to 32 volt DC power supply
(including common batteries and generators) and AC power. The
standard system detects both gamma and neutron radiation with
spectroscopic capability.
