210Pb (rad) in Inhabitants of a Caribbean Island

Abstract
The mean concentration in vertebrae of Puerto Ricans was 0.118 pC 210Pb/g ash. The value in males, 0.133 pC/g ash, was significantly higher than the 0.088 pC/g ash in females. These values are significantly lower than those in similar groups of mid-continent (Midwestern U.S.) residents, 0.196 for males and 0.156 for females. These lower values in island dwellers are attributed to the lower atmospheric concentration of 210Pb over the oceans with the consequently lower exposure to these people.
