Question

name the radioactive substance which can behave like calcium and gets concentrated in the milk of the cattle​

Answer 1

Answer:

Milk fever, postparturient hypocalcemia, or parturient paresis is a disease, primarily in dairy cattle[1] but also seen in beef cattle and non-bovine domesticated animals,[2] characterized by reduced blood calcium levels (hypocalcemia). It occurs following parturition, at onset of lactation, when demand for calcium for colostrum and milk production exceeds the body's ability to mobilize calcium.[3] "Fever" is a misnomer, as body temperature during the disease is generally not elevated. Milk fever is more commonly seen in older animals (which have reduced ability to mobilize calcium from bone) and in certain breeds (such as Channel Island breeds).[4]

Answer 2

Strontium-90

• Due to atmospheric nuclear weapon testing in the 1950s and 1960s, strontium-90 is widely distributed throughout the environment and food chain. The only way to reduce the concentration of Sr-90 in the environment is through radioactive decay. Since then, it has been gradually declining, and the levels found in the present testing are very low.
• Small levels of Sr-90 from the soil may be absorbed by plants or crops growing in or near contaminated soil. Sr-90 may be consumed by animals while consuming plants.
• Although strontium-90 can be breathed, the biggest health risk comes from ingesting it through food and water. Sr-90 can induce malignancies of the bone, bone marrow, and soft tissues around the bone. Once within the body, it behaves like calcium and is easily absorbed into bones and teeth.

Hence, Strontium-90 is the radioactive substance that behaves like calcium.
