 There is some monitoring of natural radioactivity by government
 agencies such as the Environmental Protection Agency.  There is
 a drinking water program which requires the states to monitor
 water supplies for certain types of radioactivity. The EPA radon
 program also falls in this category.  In my judgement the amount
 of monitoring is about what is needed. Most major countries have
 similar monitoring programs.
