Do the PEN Dosimeters meet any military specifications?
Yes. PEN Dosimeters are designed to satisfy military specifications for the RADIAC METER IM-264/PD and ANSI N 13.5 and N322 requirements.
Does the Charger require batteries?
No. It runs on piezo electric charges.
When charging a dosimeter, it discharges too quickly without holding the discharge button.
Clean the contacts on the Charger with a can of air or alcohol. Dust in the contacts can cause the dosimeter to discharge.
What does energy‑compensated mean?
Energy compensation provides a consistent response across different radiation energies, improving accuracy when measuring dose rates.
How many data points can be stored in the internal memory of the Inspector USB?
Total 1356. At 1 minute intervals, that’s 22.6 hours. At 10 minute intervals, that’s 226 hours (9.4 days) At 1 hour intervals, that’s 1356 hours (56.5 days)
When I put the Inspector USB in total mode, why does it not accumulate the total counts?
The latest version of the Inspector USB requires that the timer be set prior to accumulating total count. To take a timed count, follow these steps: With the Inspector operating, set the Mode switch to Total/Timer. The display shows 0 and Total in the upper left portion of the display. Press the SET button on […]
What are swipes used for with the Inspector Wipe Test Plate?
Swipe assays are routinely performed in laboratories and other facilities that use or handle radioactive materials. These assays, often referred to as smear or wipe tests, are performed to comply with radioactive material license requirements, assure laboratory safety, and provide information that proper handling procedures are being followed. Typically, swipes are performed to monitor for […]
On the Abacus, what is the “Latch” checkbox on the Alarm Settings Screen?
If an alarm is enabled and Latch is not checked, the alarm will turn on when the level is exceeded and turn off again when the radiation level dips below the alarm level. If Latch *is* checked, the alarm will stay on once the level is triggered even if the radiation level dips below the […]
How fast are the signals received by the URSA-II?
It takes about 300us to completely process a pulse on the URSA-II and most of that is sending the data via serial. The hardware pulse counter operates even while the system is otherwise busy, and provides a true number of counts and is used for applying dead time compensation. The practical limit is about 16,000 […]
Can I use an HPGe detector with the URSA-II?
The URSA-II will technically work with HPGe detectors, though it is not ideal for that purpose. The device was designed around detectors such as NaI and CdZnTe, and there is a little bit of jitter in the amplification/ADC. With an HPGe detector, you get peaks a couple of times wider than you would expect. Another […]
