Tasks Questions and Answers
Task 1
Dashboard
The dashboard provides a total of 3 visuals:
1. Map of the Mobile Sensors and Static Sensors throughout the period from 6 April 2020 to 10 April 2020
Map that provides the location of the sensors of their whereabouts since 6 April 2020 to 10 April 2020. Serves as a filter to filter the other charts. Hover to see the sensor id, its radiation value, the location coordinates, and the timestamp in minutes.
2. Radiation Measurement (Maximum) for Mobile Sensors in Minute of the Timestamp
A time-series chart based on minutes by using a sample size of maximum radiation measurement value from 0 to 5000 of the mobile sensors. Marked by colour intensity where light blue is low and dark blue is high. Hover to see the sensor id and its radiation value.
3. Radiation Measurement (Maximum) for Static Sensors in Minute of the Timestamp
A time-series chart based on minutes by using a sample size of maximum radiation measurement value from 0 to 5000 of the static sensors. Hover to see the sensor id and its radiation value.
Task 1 Questions & Answers
Visualize radiation measurements over time from both static and mobile sensors to identify areas where radiation over background is detected. Characterize changes over time. Limit your response to 6 images and 500 words.
Description | Images |
When the radiation measurement of a sensor has reached a minimum value of 100 CPM, it is at the dangerous radiation level. According to the International Nuclear and Radiological Event Scale, there are 8 classes of radiation classification as follows:
Hence, we will choose “6. Accident with wider consequences”, “7. Serious accident”, and “8. Major accident” to find out where do these radiation classifications are detected as these classifications are range from 100 CPM onwards. In the map, the blue dots indicate the mobile sensors while the orange dots indicate the static sensors. Based on the timeline of April 6 2020 12.37am to April 10 2020 11.59pm, most of the high radiation occur in the north and central part of St Himark such as:
This is most likely that the radioactive contamination has spread from the nuclear plant from Safe Town to its nearby regions. |
