Reliability of sensors

The reliability of the sensors in locating areas of concerns depends on what we are trying to determine. If we are looking to determine if the readings are reliable in helping us determine background radiation levels, then contaminated sensors might give unreliable readings. However, if we trying to determine areas where radioactive contamination might have spread to, data from contaminated sensors will be able to show us areas that are likely to be contaminated.

The dashboard above shows areas where contaminated cars have passed by. Through cross-validation, we can see that the average readings in the neighbourhood where contaminated cars have passed by are higher than readings gathered from the previous days. St. Himark officials should look to isolate contaminated cars to prevent further spread of radioactive contamination.

Number of contaminated cars

The estimated number of contaminated cars amount to xxx. These cars will be cars in possession of the following sensors:
