What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About

NanoNuke is a very small, yet highly sensitive radiation detector. It can connect to your phone via Bluetooth Low Energy (BLE). The phone provides a rich user interface (UI) and allows for time and date stamped data logging with GPS coordinates. The data can be logged to a file on your phone and it can (optionally) be logged to RadResponder. (Please note that you must have some emergency response role in order to get a RadResponder account). Other internet based databases could be supported in the future.

NanoNuke also has a small local display.

The following video shows NanoNuke connecting to GammaGuard and demonstrates various features, such as changing units, interpreting results and running and alarming in the background. Watch full screen on Youtube.

Why Would You Want High Sensitivity?

If you invest in a radiation detector, you want it to work and you want to be able to see radiation emitted by everyday items. The NanoNuke easily detects radiation emitted from an ordinary smoke alarm. You will be able to see the elevated radiation levels near brown brick buildings. You can test your granite counter tops to make sure they aren't radioactive.

NanoNuke gets around 4000 counts per minute on a smoke detector and 6000 CPM on a pack of 2% 1/8" TIG welding electrodes. 

Here is a video of NanoNuke responding to consumer items.

Do Sensitive Radiation Detectors Saturate at High Levels? What Can Be Done About It?

High sensitivity radiation detectors will max out at high radiation levels. The NanoNuke is no exception. Its response becomes non-linear at around 1000 µSv/h or 100 mRem/h. 

NanoNuke works with the GammaGuard app. The GammaGuard app can either connect to external detectors, like NanoNuke, via BLE or it can use the phone's built-in camera as a radiation sensor. In that mode, GammaGuard has been tested in radiation fields as high as 300 Sv/h or 30,000 Rem/h without saturating. 

NanoNuke is the ideal external radiation detector to use with GammaGuard. NanoNuke measures low radiation levels (0 to 1000 µSv/h or 0 to 100 mRem/h) and the phone's built in camera measures high levels (100 µSv/h to 300 Sv/h or 10 mRem/h to 30,000 Rem/h). GammaGuard's UI is the same, whether you use the internal or external detector.  

How Does it Work?

The Basics

NanoNuke uses a scintillating crystal (CsI(Tl)) coupled to a solid state photomultiplier. The CsI(Tl) scintillator is hundreds of times more sensitive than a similar sized Geiger tube. When radiation strikes the crystal, a flash of light is emitted, which is then converted to a small electric pulse by the photomultiplier. This pulse is amplified to 3V and counted by a microprocessor, which also controls the OLED display and the BLE communication.

NanoNuke runs on 2 standard AAA batteries.

Some Details

When connected to GammaGuard, NanoNuke sends count data 5 times per second by BLE. That rate allows GammaGuard to react in real time to radiation measured by NanoNuke.

NanoNuke gets about 1000 CPM per µSv/h or 10,000 CPM per mRem/h at Cs-137. It is even more sensitive at lower gamma energies and measures about 4000 CPM near a smoke detector.

NanoNuke has a dead time of 11 µs. In practice, that means that response becomes non-linear at around 1000 µSv/h. The algorithm corrects for dead time. We haven't tested NanoNuke near a really hot source, yet. 

Firmware updates can be applied wirelessly thorough the GammaGuard app.

What Other Cool Things Can You Do With NanoNuke?

Connect two NanoNukes to one phone with the GammaGuard app and use as a directional detector. We have applied for a patent on the following process:

Slip one NanoNuke into the back of your shirt and hold the other NanoNuke in front of your torso, in same hand as your phone. You then turn around slowly. GammaGuard compares the signals in the two detectors to determine the direction of the radiation source. (When your body is pointed toward the radiation source, the front NanoNuke sees much more radiation than the back detector, which is shielded by your torso.)

Prior to NanoNuke, specialized equipment that was large, bulky, complex, fragile and expensive was required to get directional information. 

The Rewards

NanoNuke (CA$450 or CA$420 (~$310 US))

This is the fully assembled NanoNuke as shown in the video. 9 cm x 5 cm × 1.5 cm in size and weighs 65 gram, including batteries. Yet, it will detect about 4000 counts per minute on a smoke detector.

NanoNuke Sensor (CA$ 350)

If you want to incorporate a high sensitivity radiation detector in your own projects and control them with your own microprocessor, this reward is for you. It includes the CsI(Tl) scintillator coupled to a solid state photo multiplier and connected to our power supply/amp board. All you need to do is supply 3V to the system and it will produce a 3V pulse for each gamma ray detected.

BotSpine Board (CA$50)

 These boards are the brains of all our instruments, including NanoNuke. Great development tool for OEMs and hobbyists. Includes an OLED display. See http://botspine.com for more info.

Project Status

NanoNuke is fully functional and tested. The Android app is available on Google Play. We currently solder our circuit boards by hand. Funds from the Kickstarter campaign will be used to get a batch of circuit boards stuffed by a contract manufacturer.

Getting the boards stuffed will take a month to 6 weeks and assembling the NanoNukes will take 2 weeks to a month. So, we expect to be able to ship sometime between 1.5 and 2.5 months after the Kickstarter campaign.

About Us

Environmental Instruments Canada is a small company of 6 people. We have been making specialized radiation measurement instruments for almost 20 years. Our products are used in uranium mines, in first response situations and radon mitigations.

Risks and challenges

The design of NanoNuke is complete and the product is tested. The Android app is fully functional and available on Google Play. The iOS version of the app is in testing. The iOS version currently does not support logging data to RadResponder or determining the radiation direction, using 2 NanoNukes. Depending on the level of interest in iOS, we may not add this functionality.

The only thing left to do is to order a production run of circuit boards. There is a risk is that the boards end up defective. In that case, we would order another batch from a different contract manufacturer. This would delay our schedule but would not compromise the project.
