SabreBZM alpha aerosol monitor

SabreBZM alphaaerosolMonitorinstrument

　　SabreBZMIt is a lightweight, battery-powered alpha aerosol meter that can be worn on the body with the sampling head clipped to the collar. This more accurately reflects the dose in the breathing area of ​​the human head and provides rapid alarm. A solid silicon detector and reliable1024The multichannel analyzer provides data toPDAPerform energy spectrum analysis, a3LPMThe smart pump and lithium battery provide greater than8hours of work.SabreBZMIt can be customized by the factory to measure the energy concentration of specialized nuclide materials or radon progeny.

　　advancedαPeak shape fitting techniques can be used to separate the spectrum into the contributions of its individual component nuclides and to quantify spectral counts by radon daughter and one or two user-defined nuclides of interest.αPeak shape fitting technology uses multipleαNuclide peaks are used to create a composite curve that best fits the current spectrum count. Because the individual nuclide peaks are judged independently, the separated nuclides are not affected by changes in radon balance and have little impact on the low false alarm rate. precisePo-218The result of the fit is, in many cases, using40LPMExcellent sensitivity at the same sampling rate.

　　Audible notifications of dose and status changes can be transmitted to the user via headphones or noise-cancelling headphones, ensuring that the user does not need to use their hands to operate the instrument and the instrument is always worn in protective clothing.

The system can handle up to10Individual personnel conduct real-time remote monitoring and measurements on site.

　　Protected with glueiPAQ PDAIt can display detailed information such as the status and readings of the instrument when it is working. The instrument displays dose evaluation and instrument status at any time. At the bottom of the window, it displays historical readings, battery status or displays the currentαSpectrum.

　　SabreBZMfor quick response (1～30seconds) and high sensitivity (1Minutes) readings in both modes are saved as well as spectra in user-defined intervals. All data can be stored in the built-in memory orSDcard for easy reading and review later. Data can be opened by most spreadsheet and database software" csv "format.

　　If an instrument is needed to measure the potential of radon daughters in the airαenergy concentration(PAEC)，SabreBZMConfigurable at the factory'Radon Mode'. The instrument can display US unitsmWL、WL-hor metric unitsµJ/m³andµJ-h/mm³, because the individual daughter concentrations are known, the effective equilibrium ratio of radon daughters can be calculated. This feature is very helpful in determining the time of the sampled gas.

　　SabreBPMThe sensitivity depends on several factors including radon background, filter paper type, flow rate and sampling mode setting (fast response/high sensitivity) and the nuclide energy of interest. The figure shows that the radon background is1.8 pCi/l, sampling in high sensitivity mode4hours of detection limit conditions.
