The analysis revealed a spike in strontium-90 levels in children born between 1954 and 1955. This coincided with a period of extensive nuclear testing that started in 1953. Among these children, strontium-90 levels were also found to be higher in those who were bottle-fed compared to those who were breastfed.

This observation further emphasized that the children were absorbing the radioactive element from the environment — picture acres of dairy farms showered with rain that has just passed through kilometers of atmosphere containing radioactive dust.

Two months later, the Partial Test Ban Treaty (PTBT) between the United States, the Soviet Union, and Britain was signed. This agreement prevented countries from performing test detonations of…
