A Review of Radioactive Strontium for Radiation Protection Purposes.

Area of Science:

• Environmental Science
• Radiological Health
• Toxicology

Background:

• Strontium, both stable and radioactive, is widespread in the environment due to natural and human activities.
• Radioactive strontium isotopes have industrial, medical, and research applications, increasing exposure risks.
• The threat of radioactive materials, including strontium, in chemical, biological, radiological, and nuclear (CBRN) events necessitates preparedness.

Purpose of the Study:

• To review current data on biokinetics, health effects, and treatments for internal radioactive strontium exposure.
• To identify knowledge gaps in strontium toxicity and medical countermeasures for radiation protection.

Main Methods:

• Critical review of existing scientific literature on radioactive strontium.
• Analysis of data on strontium biokinetics and toxicology.
• Evaluation of current pharmacological treatments for internal contamination.

Main Results:

• Strontium's ubiquitous presence and diverse applications create realistic exposure scenarios.
• Internal contamination with radioactive strontium presents significant health risks.
• Existing data highlights the need for advanced knowledge in strontium toxicity and medical treatments.

Conclusions:

• Effective radiation protection requires comprehensive understanding of radioactive strontium's health impacts.
• Further research is essential to develop advanced medical treatments and toxicity data for radioactive strontium.
• Preparedness for CBRN events involving radioactive strontium is critical for public and military safety.
