Vedclass · Answer

(C) Plants growing near nuclear test sites are known to absorb and accumulate radioactive isotopes from the soil. Specifically,radioactive $Strontium-90$ is a common byproduct of nuclear testing that is taken up by plants because it chemically mimics calcium. While some other plants are known as hyperaccumulators for elements like gold or selenium,in the context of nuclear test sites,the accumulation of radioactive strontium is the most significant biological concern.
