7. Using the Raysid App

Raysid App has 5 screens/tabs with their own functions.

7.1 Status Bar

Raysid App top bar

Bluetooth status displays connection quality by calculating the percentage of received data packets without errors. Values range is from 0% to 100%. 100% means no data packets are lost (ideal connection). 50% - half of all data packets are lost (very poor connection conditions).

GPS/Mapping status displays current status of GPS module/GPS settings/Mapping status.

Possible values:

  • off - GPS module is off (check Android OS options)
  • disabled - Map Building is disabled in Raysid App settings
  • scan - waiting for coordinates from GPS module
  • stop - no movement detected. GPS module is not used when mobile device is not moving
  • Nm - (where N is some number) Map is building. N - current GPS accuracy
Raysid temperature displays current temperature of Raysid’s circuit board. Battery status displays remaining battery percentage and estimation time (in days or hours) till full discharge.

Search screen is used to check current dose rate and CPS/CPM levels in real-time, display current accumulated dose. The bar graph represents current gamma-spectrum.

Raysid App Search Screen

Absorbed dose. First value - accumulated dose since the reset (SETS > About > Reset Accumulated Dose). Time of accumulation has the following format: days:hours:min:sec. Yearly: NNN - estimated early absorbed dose based on current average value.

Alarm Level. Above this level signalization will be triggered and alarm-event will be recorded.

CPS/Dose rate scale has format N1:N2, where N1 - CPS/CPM scale value, N2 - dose rate scale value.

CPS/CPM graph, Dose rate graph displays the last 40 seconds of CPS/CPM and dose rate values.

CPS/CPM value, Dose rate value - last values from Raysid.

Energy bars - all 1800 spectrum channels divided into 30 ranges. Every bar represents 60 channels of spectrum. Bar’s height shows current click-rate in bar’s energy range (in CPM).

High energy bar represents current rate of high energy rays (over spectrum range).

Bars scale - every energy bar height is measured in CPM in its own energy range.

Screen rotation lock - lock/unlock screen rotation.

Background bars. Disable/Enable background bars (green bars). Background-spectrum bars can be displayed when spectrum is saved (Spectrum Screen > "Save new background" button).

Take picture/video - take picture or record a video with built-in Raysid’s measurements.

7.3 Spectrum Screen

Spectrum screen is used to collect gamma-spectrum data and for measurements with low relative error.

Raysid App Spectrum Screen

Identified source. Raysid App has a per-defined library of separate isotopes and mixed sources. These sources can be identified by peaks in gamma-spectrum. Letters L(low), M(mid), H(high) mean probability of correct result.

Spectrum Counts Scale. A scale for gamma-rays received per channel.

Gamma spectrum (yellow) - current gamma spectrum collected since the last press of RESTART button.

Background spectrum (green) - saved earlier spectrum by pressing "Save new background" button.

Energy scale, keV - horizontal scale, representing gamma-rays energy. Channel values are converted to keV.

Average CPS(M) value, dose rate value - average values since RESTART button pressed.

Spectrum Information:

  • Total Counts - the amount of registered gamma rays since the last restart;
  • High Energy - the amount of gamma rays with high energy (bigger than spectrum range);
  • Time - time since the last spectrum/measurement restart;
  • Peaks - automatically identified centers of peaks (in keV) based on current collected spectrum.

Restart measurement / clear spectrum - restart data collection / reset values.

Screen rotation lock - lock/unlock screen rotation.

BG spectrum switch - show/hide background spectrum (green).

Save new background - save current collected spectrum (yellow) as background spectrum (green).

Take picture/video - take picture or record a video with integrated spectrum and measurement values.

Reset zooming - show full spectrum size (fit the screen).

7.4 Map Screen

Map screen can display current radioactivity map. There are two maps:

  • local map - user’s tracks stored in Raysid App’s data folder. No Internet required for building/displaying this map. (Internet is required just to load a Google Map)
  • global map - shared tracks of all Raysid users. This map requires an Internet connection.
Raysid App Map Screen

Raysid map scale - scale of current Raysid map.

Show my position - center map on current GPS position.

Screen rotation lock - lock/unlock screen rotation.

Show global track - display global radioactivity map from the server (http://www.raysid.com/map/). The global map contains shared tracks of all users. This option requires internet connection.

Share further track. When enabled, all further tracks will be logged and sent to Raysid global map. Shared information: date(not exact time), GPS position, radioactivity levels.

Map building 24/7. When enabled, map building will work even if the application is closed. Map building status will be visible in Android OS notifications.

Remove points. A tool for point removal. It will remove points in a selected area. Your points will be removed from Raysid’s server too. Deleting from global map may take several days because of cached data (cached by server and end-user browser).

Take picture/video - take picture or record a video with integrated radioactivity map and measurement values.

7.5 Log Screen

Raysid has a detailed log of alarm events. When bluetooth is connected, all log entries move to Android device’s storage. Raysid’s buffer can store 40 log entries. Raysid App can store thousands of log entries (limited only by Android device’s disk space).

7.6 Settings Screen

7.6.1 CPS Alarm / Dose Rate Alarm

This menu is used to enable/disable alarms, set alarm levels, select type of alarm indication (red LED, sound, vibration)

7.6.2 Clicks

Enable/Disable clicks on every registered gamma ray. Click indication: LED flashes / sound clicks.

7.6.3 Sensitivity / Accuracy

Select balance between sensor sensitivity and accuracy. Higher accuracy means bigger averaging and lower sensitivity. This option takes effect on CPS/CPM and dose rate values in Search screen and Map screen

7.6.4 Spectrum Channels

This option takes effect on spectrum. Less channels - faster spectrum collection but less graph resolution.

7.6.5 Save Background Spectrum

The same as Save new background button - save current collected spectrum (yellow) as background spectrum (green).

7.6.6 Spectrum Calibration

If you see that peaks of some known isotopes are not in their place (shifted more than 2%) then you may try to calibrate your spectrum.

Extension - this parameter may expand spectrum in the range: -5%..+5%.

Example: a spectrum of Cs137 has peaks 31keV(normally 32keV) and 653keV(normally 662keV) then try to set Extension to +2%.

Shift - this parameter may shift spectrum by -5..+5 channels

Example: a spectrum of Cs137 has peaks 31keV(normally 32keV) and 660keV(normally 662keV) then try to set Shift to +2.

Linearity - this parameter corrects peaks in the middle part of a spectrum. This parameter is necessary to change when left and right parts of spectrum are ok but the middle one is shifted.

Example: a spectrum of Th232 has peaks 80keV (ok), 242keV(should be 239), 583keV(ok). Then try to set Linearity to -3

7.6.7 Enable Map Building

When disabled, map building is stopped. The map may continue to show your position but new points will not be saved.

7.6.8 Share my track

When enabled, all further points will be saved in both: your local map(Android device) and global map(Raysid server). When disabled - all further points will be saved only in your Android device.

7.6.9 Always Running 24/7

When enabled, Raysid App will try to run in background even when the application is closed. This is required to build radioactivity map 24/7 in non-stop mode.

7.6.10 GPS Usage Optimization

When enabled, Raysid App doesn’t touch GPS module or stops map building when Android device is not moving (accelerometer is used). This helps to save battery, especially on old Android devices.

7.6.11 Base Layer

A basic layer of Google Map.

7.6.12 Raysid Layer

Radioactivity map based on values from Raysid: CPS/CPM or Dose Rate

7.6.13 Show Global Raysid Map

When enabled, map shows both: locally stored map from Android device and global radioactivity map from Raysid server. This option requires internet connection.

7.6.14 Raysid Map Detalization

This option defines the size of minimal square marker. Higher detalization means smaller markers.

7.6.15 Close Inactive App

Battery saving option. If enabled, Raysid App will close itself after 30 sec of inactivity (the app is minimized or screen is off).

7.6.16 Button Functions

While Raysid is ON, its physical button has several programmable functions. It is possible to set a preferred function for any of these actions: single press, double press, triple press. Long press = switch OFF.

7.6.17 Dose Rate Units

Two options: uSv/h and uR/h.

7.6.18 Click Units

Possible values: Clicks Per Second (CPS) or Clicks Per Minute (CPM)

7.6.19 About
