The pancake-GM workhorse for routine contamination and dose-rate surveys
Morning bench survey before the first dispensing run; afternoon-shift wipe counts; routine clean-room surface check. The pancake window picks up the low-energy beta emitters that a closed-tube probe misses.
Naturally Occurring Radioactive Materials surveys at customs, scrap metal yards and bulk material handling. The 10 keV photon threshold catches the U / Th decay products NORM monitoring expects.
Timed wipe-test counts on sealed-source surveillance wipes for AERB-licensed sources. The 9.99-million-count totaliser supports the long count times low-activity wipes need.
AERB / state radiation-safety officers running facility inspections carry a Ranger for spot dose-rate readings, contamination checks and source-leak verification. The handheld form factor + USB log meet the inspection-paperwork demand.
Lu-177 / I-131 patient discharge surveys — verify dose-rate at 1 m from the patient and at the room surface before release. The 1,000 µSv/hr ceiling covers the patient-discharge regime.
Cyclotron / hot-lab waste characterisation before AERB-compliant disposal. The Ranger reads each container before it leaves the facility, with a USB-logged result that feeds the waste manifest.
The thin mica window admits photons down to 10 keV — that catches I-125 (35 keV), Tl-201 (70 keV) and the U / Th X-ray complex that NORM screening needs. A closed-tube survey meter that stops at 50–80 keV walks past those isotopes entirely.
Every reading streams to the Windows Observer software via mini-USB — date, time, location (manual or GPS-tagged), and the count or dose-rate value. The AERB inspection log is built from data, not from operator handwriting in a survey notebook.
800 hours on two AAs at background levels means the meter lives in the hot-lab bench drawer with no charging schedule. The radiation safety officer picks it up, surveys, drops it back. The instrument is available when the survey is needed.
