Personal Radiation Dosimeter.

Tracerco T404 Radiation Monitor. Product and Interface Design.

The TRACERCO™ PED is attractive to workers who are not specially trained to measure radiation exposure, and it's safe to use to measure nuclear radiation exposure in potentially explosive environments, (Intrinsically Safe).

Everything on the dosimeter has been designed with the user in mind; the display features radiation graph measurements and a simple diagram of a man who fills with colour depending on the dose of radiation received.

Product Group create game changing design for Personal Radiation Dosimeter.
This followed the Product Group’s successful development of the Tracerco T202, T402, T406 and NORM-IS Radiation Monitors for the nuclear, mining, oil and gas industries.

The Product Group’s design team generated an inspired new interface, case design and all internal detail.

The dream:
To establish a new Personal Radiation Dosimeter benchmark to give buyers of Tracerco’s Personal Dosimeter the most compelling reasons to buy.
To create a new graphic interface, easily understood and usable by occasional and specialist users alike, thereby maximising the potential worldwide market.

To integrate audio and visual alarms with logically presented safety information, in a compact and robust wearable radiation dosimeter.

Working closely with the client the product design team identified the key requirements in developing this innovative new product.

How:
Firemen, construction workers, medical services, university science departments and many more have the occasional need to monitor levels of radiation exposure for personal health and safety.Specialists understand numbers for radiation levels and exposure, but occasional users need simple graphic information about the level of radiation, threat to health and actions to take.
The product design team explored every element; user types, health and safety requirements, required user information, audio and visual alerts, wearable technologies, waterproof enclosure standards, charging and interconnection.

Putting it all together:
The innovative interface design was developed by defining the must-have information and exploring the most intuitive visual devices to convey that information quickly and unambiguously.
An integral OLED screen displays a visual outline of a human figure representing the user. Recorded radiation fills the figure icon from the bottom with solid colour to show exposure capacity based on radiation strength. A time is given for the safe exposure period left and an audio, visual and haptic alarm reminds the user when that period is coming to an end.
A colour screen layout was developed to invite feedback from potential users, both specialist and occasional. With positive feedback to the interface proposals, these were developed and refined.

Integrating the components into a rugged, intrinsically safe (spark proof) and waterproof enclosure required precise planning and CAD engineering by the product design team.

Several steps of prototyping and testing refined appearance, functional and assembly detail.
All parts in the assembly were CAD modelled to include every detail, providing ready to use data for the toolmaking and manufacturing process.
Detailed discussions with the manufacturer solved remaining assembly and sealing issues.
