Bone and bony structures contain calcium and phosphorus. b. During nuclear tests, scientists were concerned that strontium-85, a radioactive product, would be harmful to the growth of bone in children. Explain.

Verified step by step guidance

1. insert step 1: Understand the role of calcium in bone structure. Calcium is a key component of bone, providing strength and structure.
2. insert step 2: Recognize the chemical similarity between calcium and strontium. Both elements belong to the same group in the periodic table, the alkaline earth metals, and have similar chemical properties.
3. insert step 3: Explain how strontium can replace calcium in bones. Due to their chemical similarity, strontium can be incorporated into bone in place of calcium.
4. insert step 4: Discuss the potential harm of radioactive strontium-85. If strontium-85 replaces calcium in bones, its radioactivity can damage bone cells and tissues, potentially affecting bone growth and health.
5. insert step 5: Conclude with the specific concern for children. Children's bones are still growing, making them more susceptible to damage from radioactive substances like strontium-85, which can interfere with normal bone development.

Key Concepts

Bone Composition

Bones are primarily composed of a matrix that includes minerals such as calcium and phosphorus, which provide strength and rigidity. These minerals are crucial for bone development and maintenance, making them essential for healthy growth, especially in children whose bones are still developing.

Strontium-85 and Bone Uptake

Strontium-85 is a radioactive isotope that can mimic calcium in biological systems. When present in the body, it can be incorporated into bone tissue, potentially disrupting normal bone growth and development. This is particularly concerning for children, as their bones are more susceptible to changes and damage during critical growth periods.

Radiation Effects on Health

Exposure to radioactive materials like strontium-85 can lead to harmful health effects, including increased risk of cancer and developmental issues. In children, whose cells are rapidly dividing and growing, the impact of radiation can be more pronounced, making it vital to monitor and limit exposure to such isotopes to protect their health.
