Radiation Dose Advisor Application


TECHNOLOGY AREA(S): Bio Medical, Nuclear

OBJECTIVE: DTRA is interested in developing a simple electronic application or toolkit that is able to run on a hand held electronic device in conjunction with a radiation detector to provide stay time and health hazard decision making support to individuals in unknown or varying radiation fields.

DESCRIPTION: Often radiation fields can vary or are unknown in emergent situations where first responders and other individuals must still be able to perform critical operations. This application is intended to take real time radiation sensor data (to include the dose rate and accumulated dose), any optional user input such as any dose restrictions for the responders, and then rapidly run calculations to compare against a set of safety guidelines to then display a stay time in the current area and display any applicable health warnings based on the dose accumulated.This application should be able to: 1) Run on a tablet, computer, smart device, or smartphone with windows or android operating system or a given operating system and be networkable 2) Collect and process radiation sensor data sufficiently to extract dose and dose rate data 3) Given a set of safety guidelines, incorporate the threshold values as references 4) Use the reference values, accumulated dose from the detector, user defined restrictions on allowed dose, and dose rate from the detector to calculate a stay time in the current location. 5) Taking the accumulated dose calculations from 4) and then compare against other overall reference values to determine any health hazard warnings 6) Display percent of allowed dose accumulated 7) Display stay time 8) Display any health hazard warnings that can be acknowledged and minimized. 9) Share the calculated data on the network to other users 10) Update calculations on flexible frequency, faster at high dose rates, slower at low dose rates 11) Have reference values updated as needed

PHASE I: Identify and demonstrate pathways for meeting the performance goals at the end of Phase I. Incorporate the provided safety guidelines and ability to accept user defined restrictions into the application and demonstrate the calculations can be done with simulated detector data.

PHASE II: Using progress from phase one, use actual detector data and user defined limitations to demonstrate stay time, percent of allowed dose, and any warnings will display on user smart device.

PHASE III: This has numerous applications for any individuals needing to work in unknown or rapidly changing radiation fields, such as local, state, and federal first responders and emergency response personnel at power plants and other nuclear facilities.
