MINI-CHALLENGE 2: CITIZEN SCIENCE TO THE RESCUE
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.
Given the question, I have plotted every minute of each day in the data provided. With the merger of the dataset with the Neighbourhood data, this is the level of radiation plotted over a 5 Days period. There are two types of sensors used to pick up the readings, the line denoted in blue is by the mobile sensor and the line in orange is picked up by static sensors. Across every graph plotted, there is a dotted red line. The red line is set at a value of 75 CPM, which means that any data point plotted above that value means that the radiation is very dangerous.
On the 6th April, we can see that the radiation across all neighbourhoods is relatively safe, with some spikes in the data point which lasts less than a minute. Hence there is nothing out of the blue on the 6th April.
On the 7th April, everything was similar to the 6th of April, everything is relatively safe with some random spikes in the data. Hence everything seems normal on 7th April.
On the 8th April, we can see a sharp spike in the radiation levels at Safe Town from 1:21 P.M. to 4:30 P.M. before Old town had a similar spike at 4:55 P.M. all the way to 9:28 P.M. Other then this two towns which has a prolong period of unhealthy radiation, the rest of the town seemed ok. Coincidentally, the nuclear powerplant is located at Safe Town and Old Town is situated right beside Safe Town. We can generally summarise that winds were blowing westwards.
On 9th April, we can see Safe Town has a sudden spike in radiation, tending towards the unhealthy zone and the neighbourhood Scenic Vista had a huge fluctuation of radiation alternating between the healthy and unhealthy range. The place that took the worst hit was the Wilson forest with an average of 1,093 CPM for the day. The radiation was 14 times over the unhealthy limit. From the two town hits on the 9th April, we could say the wind was travelling in a curved shape.
On 10th April, We can see that the only two towns still being affected by unhealthy radiation are, Wilson forest and Scenic Vista.
