Analysis
Question 1
Visualize radiation measurements over time from both static and mobile sensors to identify areas where radiation over background is detected. Characterize changes over time.
The chart above shows the average radiation of the mobile sensors (blue line) and static sensors (yellow line) by Neighbourhood. The red line is the 75cpm mark whereby any value beyond that point is abnormal.
As seen from above, from the 9th to 10th, Wilson Forest has spike in the radiation readings with an average value of 1093cpm on the 9th and 1258cpm on the 10th while the rest are under 54 and 72 on the 9th and 10th respectively.
As the readings for Wilson Forest is very high on the 9th and the 10th, I decided to uncheck Wilson Forest to further analyse the other days.
For the analysis above, sensor id M12 has been filtered out (explained in Question 2).
Even though the average reading on the 6th of April are below 75cpm, there are certain spikes in certain neighbourhoods such as Broadview, Chapparal and Palace Hills etc.
Similarly, on the 7th of April, there are also a few peaks at certain neighbourhoods such as Broadview and Chapparal whereby they exceed 75cpm.
The more extreme readings can be seen on the 8th of April in Old Town whereby the mobile sensor readings spiked to 264.4, which the readings were above 75cpm from 5:30PM to 9:30PM.
Also, in Safe Town, there was a spike to 193.2CPM, which the readings were above 75cpm 1:20PM to 4:30PM. Apart from those towns, more towns have a radiation level exceeding 75cpm at certain timings.
