Storage Conditions, Precautions, and Pharmaceutical Applications of Radioactive Substances

Storage Conditions:

1. Shielding:

   • Use appropriate shielding materials to reduce radiation exposure.
   • Lead containers or bricks are suitable for gamma emitters, while plexiglass or acrylic is effective for beta emitters.
   • Alpha emitters can be stored in sealed containers as they can be blocked by container walls or even paper.

2. Ventilation:

   • Store radioactive materials in well-ventilated areas to prevent the buildup of radioactive gases like radon.

3. Segregation:

   • Store radioactive substances separately from other chemicals in designated areas.
   • Different types of radioactive materials should be kept separate, clearly labeled, and organized.

4. Restricted Access:

   • Limit access to storage areas to authorized personnel who have received appropriate training in handling and safety procedures.

5. Monitoring:

   • Conduct regular radiation monitoring in storage areas to ensure radiation levels remain within acceptable limits.

Precautions:

1. Training:

   • Ensure personnel handling radioactive materials receive proper training in radiation safety, handling procedures, and emergency response.

2. Personal Protective Equipment (PPE):

   • Wear appropriate PPE, such as lab coats, gloves, and safety glasses. Additional protective clothing, like lead aprons, may be necessary for handling gamma emitters.

3. Dosimetry:

   • Workers should wear dosimeters to monitor radiation exposure levels.

4. Contamination Control:

   • Cover work surfaces with absorbent, disposable materials to contain spills.
   • Regular surveys should detect contamination, and proper decontamination procedures should be followed if needed.

5. Waste Disposal:

   • Segregate, collect, and dispose of radioactive waste according to local regulations and guidelines.

Pharmaceutical Applications:

1. Diagnostic Imaging:

   • Radioisotopes like technetium-99m and fluorine-18 are used as tracers in imaging techniques such as SPECT and PET scans.

2. Radiation Therapy:

   • Radioisotopes like iodine-131 and yttrium-90 are used to treat cancer by delivering targeted radiation to malignant cells.

3. Radiopharmaceuticals:

   • Drugs containing radioactive substances used for diagnostic and therapeutic purposes, requiring strict manufacturing and regulatory control to ensure quality, safety, and efficacy.
