Investigating Patterns in Data
During the last half of the 20th century, several sites in Nevada were used for testing nuclear devices (i.e., dangerous nuclear devices were exploded on those sites). Nuclear explosions spread dangerous radioactive particles in the air, which settle on the ground; this is dangerous to living things in that area until the radioactive material decays. Testing ended around 1985, so no new radioactive sources were added after that time.
The data in the table and graph [on the next page] give the amount of radioactivity measured at various times. Radiation quantity is measured in milliroentgens (mR). Because radiation exposure is dangerous as it accumulates, these data are measured in mR/year, which is how many mR a person staying on that site for a full year would receive.
(Note: These data are from Position N-8 in Area 2 of the Nevada Test Site of the U.S. Department of Energy.)
Data are based on data gathered from U.S. Department of Energy. (2009). Nevada test site environmental report 2008
