Mirion AccuRad PRD
Personal radiation detector · Hp(10) and H*(10) versions
A discreet and robust gamma radiation detector, designed for law enforcement and first responders to interdict nuclear and radioactive materials. It clips to the belt for the whole shift, alarms on a genuine threat, points you toward the source, and keeps measuring dose and dose rate when an event turns radiological.
Built to ride on the belt, not in the truck
Mirion states the AccuRad PRD was developed in close collaboration with state and federal law enforcement and first responders, to integrate into their routines. That shows in how it is carried: light, clipped on, readable without unclipping, and fed by ordinary AA cells.

01Clip on
Seven ounces, with the clip
The unit measures 4.25 x 2.4 x 1.4 in. (108 x 61 x 36mm) without clip and weighs 7 oz (200 g) including it. A tough, built-in belt clip fixes it securely to a belt or pocket, and the clip itself is a replaceable fiber-reinforced part.

02Glance
Two screens: one for your hand, one for your belt
A large front display for handheld work, plus a top display that enables hands-free visual readout and alarm assessment. Users can glance at a reading without removing the AccuRad PRD from their belt or pocket.

03Work
Five big buttons, one hand, thick gloves
Comfortable for one-handed operation and usable with thick gloves and reduced visibility (gas mask). Mirion describes the controls as intuitive to use even without training, and device data is saved automatically with no operator action required.
-
04Outlast
Two AA batteries for > 900 hours of continuous operation
A tool-less battery cover and commercially available cells: AA (LR6) 1.5 V alkaline, lithium 1.5 V (non-rechargeable) or NiMH 1.2 V (rechargeable). The USB-C port recharges NiMH cells; Mirion refers users to the operating manual when using different battery types.

05Endure
Dust, immersion, drops and cold
Resistant to dust, sand and moisture, with shock resistance from the PRD body.
IP67 · dust and 1 m (3 ft 3 in.) water immersionDrop: 1.5 m (4 ft 11 in.) on concrete-13 °F to 140 °F (-25 °C to 60 °C)
Not for explosive atmospheres. The AccuRad PRD is not certified for explosive atmospheres. Plan its use around your department's hazardous-location procedures.
Quiet all day. Loud when it counts.
An always-on detector is only useful if people trust its alarms. The AccuRad PRD uses Variable Background Suppression (VBS) so it can work in diverse background environments and trigger an alarm only for genuine threats or hazards.
Four ways to get your attention
The PRD triggers selectable audible, visual and/or vibration alarms, with one-touch alarm acknowledgment and automatic data recording.
-
Vibration
Silent, on the body.
-
Visual LED
Bright LED alarm indicators.
-
Audible
85 dB(A) at 30 cm (11.8 in.).
-
Display
Display messages.
For covert work. Discreet mode silences alarms for stealth applications: by default, the audible and visual alarms (LEDs) are deactivated while the vibration and display messages stay active. USB-C headphone connectivity adds a further level of stealth operation.
Low, high, danger
Besides dose rate or count rate, the PRD can show a simple unit-less 0–9 indicator. The default alert levels:
- 93.213
- 81.664
- 70.863
- 60.449
- 50.235
- 40.125
- 30.068
- 20.038
- 10.023
- 00.009
Default values; bar lengths show order, not scale. Device settings can be changed through the AccuRad app and the AccuRad Management center. Alarm actions on the device are suggestions and should not replace operator procedures and CONOPS.
From alarm to source
Take it off the belt and switch to Search mode. Built-in directionality helps locate hot spots in busy environments, and with audible and vibration alarms on, the PRD chirps faster as you move closer to the source, so your eyes stay on the search.
-
Step 1 · Turn
Build the radar
Holding the PRD by hand, turn left or right to build the radar sectors.
-
Step 2 · Read
Follow the black sectors
Sectors indicate source intensity versus direction; black sectors and arrows indicate the direction.
-
Step 3 · Close in
Walk it in, then switch to Trend
Go in the direction of the black sectors and arrows to localize the source, then use the Trend screen to pin down a close-by source.
Count rate (Search mode): 0 cps to 160 000 cps. The radar is calibrated in the factory before delivery and ready to operate; a built-in radar calibration module is under Settings > Service > Radar Calib.
Tap to pair. Share the picture.
The AccuRad PRD pairs with a smartphone through the AccuRad app, giving real-time remote access to measurements and alarm history, plus data logging, batch processing, messaging and reachback to common operational data platforms.

Keep it out of sight
For event security, Mirion suggests personnel in plain clothes consider carrying the PRD covertly in a pocket or backpack and getting alarms and dose rates through the AccuRad PRD smartphone application.
The app also bridges responders on the ground and command-center software with real-time geospatial and radiological data relay. The PRD is compatible with RadResponder, Sigma and SpirVIEW Mobile software.
AccuRad Management center
The desktop software handles device configuration, maintenance, data retrieval and batch configuration of a fleet of devices. Communication needs no configuration: plug the AccuRad into the computer with a USB-C cable. Mirion states that hundreds of devices can be customized within minutes.
Hp(10) or H*(10): pick the dose quantity
The AccuRad PRD comes in two versions that differ in the dose quantity they report and the standards they are rated to. Both work as a personal radiation detector and a body-worn dosimeter; the H*(10) version adds ambient dose equivalent for survey work.
Personal radiation detector
Early warnings of hazardous radiation levels; search capabilities guide responders to locate and address radiation sources.
Dosimeter functionality
When body-worn, continuously provides dose rates and dose measurements and can trigger an alarm when exceeding a safety threshold.

Personal radiation detector
The same early warnings and search capabilities as the Hp(10) version.
Dosimeter functionality
When body-worn, continuously provides dose rates and dose measurements and can trigger an alarm when exceeding a safety threshold.
Low dose rate survey meter H*(10)
Helps responders assess safe exposure limits and establish safe zones in public areas.
Micro rem meter H*(10)
Near nuclear facilities, acts as a tissue-equivalent survey meter measuring up to 10 MeV. High-energy photon measurement compliant with IEC 60846-1.
