D3S wearable personal radiation detectors

Protect your team and your citizens from radiological threats and secure your borders from nuclear smuggling.

D3S wearable personal radiation detector

The D3S is ready for your mission, whatever your mission.

The D3S range of personal radiation detectors replaces PRD personal radiation detectors, SPRD spectroscopic personal radiation detectors and RIID radioisotope identification device with ONE device that fulfils all these functions.

The D3S PRD can function as a search only dose measurement PRD but at the press of a button in the app it can also show isotope identification and with an over the air app upgrade transforms into a fully featured RIID with reachback and emailable report files including pictures. This makes the D3S range one of the most flexible and cost-effective radiation detection solutions available today.

Choose the model you need now and upgrade later.

D3S PRD personal radiation detector

D3S PRD

Designed for first-line users

One of the most capable PRD and SPRD you will find. The D3S PRD can operate in two modes:

1.Search Mode: displays gamma dose and neutron count.

2. Search and Identification Mode: displays gamma dose, neutron count, isotope identification and classification.

The D3S PRD can be transformed into a full D3S ID with full RIID capability with a simple over the air update to the smartphone app.

3S ID radiation detector for CBRNE professionals

D3S ID

Designed for radiation specialist

One of the most powerful RIIDs available.

The D3S ID has a more powerful detection app that allows the user to enter confirmation mode to take a more detailed scan of the source or sources to give the user full confirmation and reachback reporting capability.

All in a matter of seconds.

 

 

D3S NET networked gamma neutron detector and phone app

D3S NET

Networked radiation detection solution

All the power of the D3S detector now networked.

The D3S NETs location, alert status and radiation reading are connected to the SIGMA Network and are all relayed back to a central command screen.

The command screen is accessed through a secure web server so all the user need is an internet connection.

 

 

Easily switch from PRD to full ID RIID mode to NET mode with a software upgrade. No need to change the detector or the mobile phone.

D3S part of a total radiological protection solution

Networked radiological threat protection

Harness the power of the SIGMA Network and Kromek to protect a city, border or critical infrastructure.
Using the SIGMA Network, multiple detectors of different types can be networked together to provide a complete radiological map and alert system across a large area, including D3S NET concealable wearable detectors that can go anywhere a terrorist can lurk.

D3S technical specifications

These specifications are common across all D3S models

Gamma detector material: CsI(Tl).

  • Gamma energy range: 30 keV to 3 MeV.
  • Gamma sensitivity for Cs137: 5 cps/μR/h (500 cps/μSv/h) Photo peak 1.2 cps/μR/h (120 cps/μSv/h).
  • Maximum throughput for gamma channel: 10,000 cps.
  • Maximum dose rate: 2.0 mR/h (20 μSv/h) at 662 keV (spectroscopic).
  • 100 R/h (1 Sv/h) at 662 keV with high dose module.

  • Neutron detector gamma rejection: Better than 10-7 meets ANSI N42.34 section 6.7
  • Maximum throughput for neutron channel@ 5,000 cps

Library far exceeds ANSI and international standards.

42 isotopes – 22 more than ANSI N42.34 standard.

Discriminates between Medical, NORM, Industrial and SNM classes.

69 unique signatures which account for shielding and mixed configurations.

See the full isotope list here.

The Android phone radiation detection analysis app for the D3S is designed to be easy to use and has a common interface between the D3S PRD and D3S ID version of the device. This makes it much easier to move from the D3S PRD to the full D3S ID version which gives you full confirmation mode, reachback and reporting capability, all you need to do is update the app the ID version.

See the full description of the app on this page.

Search mode isotope ID within 3 seconds. Three-second rolling average to detect and identify sources of radiation.

Confirmation mode complies with ANSI 42.34 within 30 seconds.

Superior false alarm rejection meeting ANSI N42.32 for the gamma and neutron channels independently.

D3S classifies and categorises industrial, medical, NORM and SNM isotopes.

There are a lot of radioactive isotopes out in the world. You need to know what you are facing.

No one wants to cause a full-scale alert over a truck of bananas or an old lady that has just come from the hospital.

Radioactive substances are used in medical devices and treatment, industrial tools used in the workplace and in products you have in the home. Some locations are also more naturally radioactive than others.

The D3S classifies the radioisotopes it finds into:

  • Medical: isotopes used in medical treatment or medical machines.
  • NORM (Naturally Occurring Radioactive Material) is material which occurs naturally or created by activity such as burning coal, making and using fertilisers, oil and gas production or mining.
  • Industrial: isotopes used in equipment or testing or some other industrial process. A common example is devices that use a radioactive isotope to test moisture levels or depth levels in building material.
  • SNM classes (Special Nuclear Material): material that has direct use in a clandestine fissile explosive or for its use in the production of nuclear material for use in a fissile explosive.

Armed with this knowledge the first responder can act appropriately. In each, every case speed and accuracy of detection is important as is the ability to reach back to get more specialist help if needed.

A radioactive substance used in a terrorist attack is likely to be shielded to prevent its detection by gamma radiation detectors; it is vital that any detectors carried can detect neutrons as well as identify the radioactive isotopes found.

Gamma radiation can be blocked by several centimetres of lead, concrete or steel.

Neutrons need several feet of water to block them if someone is intent on doing harm they will probably shield the gamma radiation source to escape detection but the D3S will still spot them.

Unfortunately not for the PRD version of the D3S.

But the ID version has a full reporting confirmation and reach back mode, which saves the location (longitude and latitude) from the phone’s GPS.

The D3S detector isn’t designed to store the data by itself. It is connected to the phone through Bluetooth and saves a .csv file every hour, which contains every one second spectrum from the last hour. A “detection log” file is also saved, which stores when the algorithm detected the presence of a gamma source or a high neutron count.

The D3S in search mode uses roughly 0.5gb in a twelve hour shift, so 1gb a day will mean a 32gb phone can last a month, before having to download the information to an external device.

If the Bluetooth connection is lost, it aggregates the spectra. For example if the link is lost for a minute, the detector will continue to build up one spectrum, until the phone is reconnected. The phone will then pull off the one minute spectrum. It can continue to do this for whichever comes first: 49.7 days, or until one of the bins gets full, and each bin (gamma channel or neutron counter) can hold 65534 counts.

We’re able to identify 1mCi sources from close to 15 metres (16.4 yards) away.

The D3S is available in English and Japanese: text and speech
