Question

Cesium-137 and Strontium-90 are both produced in nuclear fallout. Cesium-137 has a half-life of 30 years. Strontium-90 has a half-life of 28 years. Strontium-90 is considered to be a greater health threat because cesium-137 has a longer half-life.

a. strontium is chemically similar to calcium but is more readily removed from the body than calcium .
b. cesium-137 is not radioactive.
c. strontium is chemically similar to calcium and is incorporated into bone.

Answer 1

c. strontium is chemically similar to calcium and is incorporated into bone.

Step-by-step explanation:

Strontium is a chemical element in group two which bears a great similarity with calcium in terms of chemical reactivity, ion size, etc. Hence it can easily replace calcium in the bone, causing a great damage to the individual because of its radioactivity.
