GEO 1207 SMU Radon and Uranium Environmental and Health Issues Discussion.
In Class Assignment
As you know Radon and uranium in well waters can be an environmental and health issue.
1) In Nova Scotia there are several types of uranium occurrences. Look at the map 1 of the
province and list the various deposit types and give their general location. What rock types might
host the different deposits
Plot the numbers beside each well site on the map for example
N .018 U
The limit for uranium in water has been determined to be 0.02 ppm. Draw an all inclusive
polygon (or contour) around all of the well sites greater than the acceptable limit. (Use pencil or
The limit of radon that is considered safe is 1900 bacquerels per litre. Draw an all inclusive
polygon around all of the well sites greater than the acceptable limit. (Use a different colour
pencil or coloured pen than used for uranium).
How do the two contours correspond to each other? (Shape, size, rock type)
There are numerous building lots available in this area. If radon and uranium were the main
criteria for location, where would you build your house and w
