Utility description: Xe-127 Production Yield & Purity Analyzer

Xe-127 Production Yield & Purity Analyzer — Xe-127 Production Yield and Purity Analyzer

ℹ️  Utility controls cyclotron production process of Xe-127:
    • Specific yield (MBq/uAh)
    • Radionuclidic purity (% Xe-127)
    • Impurity levels (Xe-125, I-123)

⚠️  CRITICAL: Xe-125 has a long half-life!
    Its presence increases patient radiation dose without diagnostic benefit.

Usage:
  Xe127ProductionYieldAndPurityAnalyzer.exe                            → demo mode (console output)
  Xe127ProductionYieldAndPurityAnalyzer.exe input.csv output.json      → evaluate your data

Input format:
BatchNumber,ProductName,Iodine_Mass_g,Beam_uA,Time_h,Act_Xe127_MBq,Act_Xe125_MBq,Act_I123_MBq,Min_Yield,Max_Xe125_Percent

Example:
  XE127-PROD-2026-001,Xe-127,1.0,20,2,2200,10,5,50,1.0

— WHY IS THIS NEEDED?
Xe-127 production control is critical for nuclear medicine:
• Xe-127 is produced by irradiating iodine targets with protons on a cyclotron
• Process must be efficient (high yield) for economic viability
• Side reactions lead to formation of Xe-125 and I-123
• Xe-125 (T1/2 ~17 h) creates unwanted radiation burden
• Utility helps optimize irradiation parameters and control raw material quality

⚠️  CRITICAL:
• Specific yield ≥50 MBq/uAh (depends on beam energy)
• Radionuclidic purity ≥99%
• Xe-125 impurity ≤1%
• Beam energy control to minimize threshold reactions

Key features:
• Specific yield calculation based on beam parameters
• Radionuclidic purity assessment via gamma spectrometry
• Specific impurity monitoring (Xe-125)
• Support for various iodine target types

Critical parameters:
• Specific Yield: ≥50 MBq/uAh
• Purity: ≥99%
• Xe-125 Impurity: ≤1%

💡 Usage tips:
1. Use high-purity targets to reduce side isotope formation
2. Precisely calibrate beam current and irradiation time
3. Perform gamma-spectrometric analysis immediately after end of bombardment (EOB)
4. Account for decay of short-lived impurities before product release
5. Maintain yield log for each cyclotron energy setting

⚠️ Note: Unlike reactor production, cyclotron production allows carrier-free isotopes but requires strict beam energy control to avoid "hitting" adjacent nuclear levels. The utility helps maintain this balance.
