2 Origins of the project

 AGE CNEA-CAE requires a surface dose rate map  Large measuring area (8km2), requires automated process  Requires periodic measurements  Due to possible high dose levels prefer to reduce the exposure of people  GIAR works on a project for multipurpose flying vector

SLIDE 3

3 Particular conditions

 Rough terrain  Inaccessible areas and obstacles (perimeter fencings)  Requires static measurements (depends on detector volume vs exposition time)

SLIDE 4

4 Objectives of the project

Mechanicals

 Light  Robust

Measurement

 Count measurement with geospatial reference  Detection efficiency  Telemetry

SLIDE 5

5 Requirements of project

Navigation

 Autonomy  Controllability (altitude, full featured AP, secure mode, inertial NAV)  Telecommand (power off of not used modules)

Auxiliar systems

 Real time Video Link

7 Main Features

 Sonar obstacle avoidance system  Sonar altimeter  AHRS system (IMU)  Video link  Autopilot  Real time telemetry and telecommand  Entirely designed and build by us. All materials available off-the-shelf  Up to 6 hours autonomy  Easy scalability (more Helium, more payload)  Very low cost (USD 600), without detector

SLIDE 8

8 Legal, regulatory and safety

 ANAC (National Civil Aviation Association) (UAV, Res. Nº527/2015)  Helium (instead of heated air or Hidrogen)  Negative floatability  Secure mode Auto Pilot (3 modes)  Shut-off  Return to base  Secure landing

SLIDE 9

9 Other features

 3D surface map  Gamma Ray Spectrometry  Microcontroller based for low count rate  FPGA based for high count rates

SLIDE 10

10 Future Works

 Plastic detectors  Silicon PMT  High precision GNSS (Global Navigation Satellite System)  Relation between measure time and weight of scintillator material and volume  Background characterization

Calibration

 Measure counts by a Scintillator (NaI(Tl))
