Study Notes
Radioactivity
- Definition: The process by which unstable atomic nuclei lose energy by emitting radiation.
-
Types of Radiation:
- Alpha particles: Heavy, positively charged particles; low penetration.
- Beta particles: Light, negatively charged particles; moderate penetration.
- Gamma rays: High-energy electromagnetic radiation; high penetration.
- Half-life: The time required for half of a radioactive substance to decay.
-
Applications:
- Medical imaging (e.g., PET scans).
- Cancer treatment (e.g., radiotherapy).
- Tracers in biological and chemical research.
Radiopharmacy
- Definition: The branch of pharmacy that focuses on the preparation and dispensing of radioactive compounds for medical use.
-
Key Components:
- Radiopharmaceuticals: Radioactive drugs used for diagnosis or therapy.
- Preparation: Involves strict protocols to ensure safety and efficacy.
- Quality Control: Ensures radiopharmaceuticals meet regulatory standards.
-
Uses:
- Diagnostic imaging (e.g., SPECT and PET).
- Therapeutic applications (e.g., targeted radiotherapy).
- Regulations: Governed by health authorities to ensure patient safety.
Quality Assurance
- Definition: A systematic process to ensure quality and safety in the production and use of radiopharmaceuticals.
-
Key Elements:
- Standard Operating Procedures (SOPs): Detailed instructions for routine operations.
- Validation: Process for ensuring that methods and equipment perform as intended.
- Quality Control Tests: Include potency, purity, sterility, and stability assessments.
-
Importance:
- Ensures patient safety and treatment efficacy.
- Compliance with regulatory standards (e.g., FDA, EPA).
- Minimizes risks associated with radioactive materials.
Interconnections
