The new Thermo Electron EPD-N2combines excellent photon dosimetry with full-spectrum neutron response, making thisdosimeter ideal for those working inmixed neutron/gamma fields. EPD-N2™
Electronic Personal Gamma-Neutron
Dosimeter
- Advanced radiological performance, 25keV-10MeV (photon), thermal – - Excellent performance in mixed gamma/neutron fields - Excellent performance for low-dose measurements - Direct display of Hp(10) for neutrons and for photons - Outstanding immunity to electromagnetic interference - AA battery, lithium or alkaline, interchangeable - Compatible with current or upgradeable Thermo Electron EPD readers, Analyze • Detect • Measure • Control™
- Sensitive to x- and γ-radiation (E > 25keV) and neutrons - Display and enabled functions controlled by button on front face of EPD - Direct readout of Hp(10) for neutron & photon dose - Multiple diode detectors with converters and energy compensation shields - Display units: Sv & rem (with prefixes µ, m), set via internal software - Generally in accordance with ANSI standards 13.11, 13.27 & 42.20 (photons performance) and most aspects of IEC 61525 (neutrons & photons) high impact plastic, easily renewed, strong - Dose display & storage 0µSv to > 16Sv, auto-ranging - Resolution for display: 1µSv (< 10mSv/1rem) ( γ, and neutron under best - Resolution for storage: 1/64µSv (~1.5µrem) (γ), 1µSv for neutron dose - Dose rate display: 0µSv/h to > 4Sv/h (400rem/h), auto-ranging, variable Photon dose rate (2 ), photon dose, combined photon + neutron dose, neutron dose rate, over-range, failure, count - down timer, low Alarm tone, pattern, sound level, mutability - ‘Beep’ for γ-dose with configurable sensitivity- Alarm sounder: sealed, typically 97 dB(A) @ 20cm on ‘loud’ - Short term and Total dose registers for Hp(10) γ & n - Storage of peak photon & neutron dose rates, with date & time 8h/24 with use of ‘OFF’ standby state: - 23 most recent alarms or events stored with date & time ~ 500 dose data points for γ & neutron dose Assumptions: average dose rate < 5µSv/h (<0.5mrem/h), IR communications < 5s, 2x/day, audible alarm sounding <2h total during battery life With a single calibration, the neutron dose estimated by the EPD- N2 will be within approximately + 30% of the true value for many workplace fields IP55 (protection against dust ingress & low pressure jets of water from all directions) - Internal detector self -test under CPU control Exceeds MIL STD 461D RS103; » IEC 1283 & This specification sheet is for informational purposes only and is subject to change without notice.
