2 » Introduc6on to Radia6on and Radia6on Detec6on» Limita6ons of Current Approaches» SmartPhone and Tablet Capabili6es 2

3 » Radia'on: the release of energy, in the form of a par6cle or photon, taking an atom from an excited state to a more stable state» Ionizing Radia'on: is radia6on of sufficient energy to electrically charge another atom, by causing it to lose a proton or electron. alpha, beta, gamma, X- ray and neutron radia6on» Non- Ionizing Radia'on: is radia6on without sufficient energy to ionize other atoms. Microwaves, visible light and ultraviolet light 3

4 » Emission of alpha par6cle (helium nucleus) from a heavy atom» Very low range (cm)» Shielded by paper, skin, air» Internal hazard 4

5 » GM Counters» Air propor6onal counters» Scin6llators ZnS(Ag) 5

6 » Emission of an electron» Range of several meters» Shielded by low Z material Plas6c Water» Internal hazard» External hazard to skin, eyes 6

7 » Plas6c Scin6llators» Geiger Mueller detectors 7

8 » Emission of a high energy photon from the nucleus of an unstable atom» Very high range in air» Shielded by heavy, dense material Lead Concrete» External hazard 8

9 » Ioniza6on Chambers» Scin6lla6on Detectors» Germanium Systems 9

10 » Emission of neutron par6cles, oten the result of a fission event» High range in air» External hazard 10

11 » Propor6onal Counters (He- 3) 11

12 » Standard portable radia6on detectors: Provide gross results (total exposure, exposure rate, cpm) What do these measurements mean? + LiZle to no suppor6ng assessment of data provided by instrument. Crude screening based on generic criteria» Current radionuclide iden6fiers: Provide an ini6al, limited iden6fica6on of radionuclides screening for NORM, Industrial, Medical, or Special Radionuclides But lizle else. 12

13 » For more meaningful results, requires: Advanced detectors and equipment Expert evalua6on with addi6onal data» Where is this Expert? Not immediately available and even this analysis takes 6me. 13

14 » Mobile technology is ubiquitous» Individuals are very comfortable with the use and opera6on of smart phones and tablets» No need to integrate computa6onal capability into detector when everyone already has the technology already in their pockets 14

15 » Computa6onal Capability Compu6ng/analy6cal power of standard smartphones can perform analysis of radia6on data/measurements Track/trend measurements over space and 6me Spectral analysis and evalua6on» GPS Posi6oning Loca6on services inherent in smart phone technology allow for simple integra6on of survey and mapping data 15

16 » Data messaging and transmission Bluetooth technology allows for wireless, remote monitoring of survey data by Smart Phone or Tablet. Wireless, cellular link allows for almost instant messaging and transmission of data App allows simple update to sotware, as necessary» Data Storage Standard or expandable memory allows survey data to be tracked and trended for very long 6mes Provides QA and post processing of data 16

17 is the latest in portable radia6on detec6on, measurement and analysis technology 17

18 » Built- in 1 x 1 Na(I) scin6llator detector» LaBr detector available for enhanced radionuclide iden6fica6on» Controlled by Android app on any standard smart phone or tablet 18

19 » Small, portable, lightweight radionuclide iden6fier PLUS MORE» Using power/capabili6es of smart phones and tablets Data storage and transmission Tracking and trending data GPS mapping 19

20 uses Android computa6onal abili6es to perform spectral analysis iden6fying and quan6fying radionuclides» Dis6nguishing between NORM and a Concern 20

21 » More than just an Indicator/Iden6fier» Quan6fy measurements using standard geometry coun6ng jig» Supports In- field screening using quan6ta6ve results» Dis6nguish between natural radia6on and something of concern. 21

22 » App- based sotware allows single detector to be used by any number of devices» Real- 6me, in- field screening and assessments» Automated messaging and data uploading to Cloud» Can be carried by hand, in a pocket or backpack» Can be used without the knowledge of others in the vicinity» Can be mounted in single loca6on for long term monitoring, tracking and trending 22

23 » GammaSight provides data in ANSI N42.42 format» Supports development of Specific Apps to meet project and mission needs 23
