１. 英語講義

Liquid scintillation analyzer is common instrument to measure radioactivity of beta-emitting nuclides, such as ³H and ¹⁴C.
In this presentation, I show basic information to improve understanding of liquid scintillation counting (LSC).

• Theory of liquid scintillation counting
• How does an LSC cocktail work?
• Separation of signal and noise (What is background?)
• Absolute and relative values
• Sample preparation methods
• LSC cocktail selection
• Trouble shooting for Chemiluminescence
• New information about ultra-low background measurement
