- Toxicology: Used for detecting and quantifying toxins and their metabolites in biological samples.
- Environmental Testing: Applied in measuring trace amounts of environmental contaminants and pollutants.
Operating Principles
The RIA IP.8 operates on the principle of scintillation counting. When a radioactive sample is placed in the detection chamber, gamma rays emitted by radioactive labels (typically I-125) interact with the sodium iodide thallium-activated [NaI(Tl)] crystal. This interaction produces light photons in proportion to the energy of the incident radiation.
These light photons are then converted into electrical pulses by a photomultiplier tube. The amplitude of each pulse corresponds to the energy of the original gamma ray. The counting electronics analyze these pulses to determine the number of radioactive decays occurring per unit time (counts per minute or CPM).
The IP.8 incorporates advanced pulse shape discrimination technology to distinguish between true sample counts and background events, improving measurement accuracy. The digital signal processing system applies sophisticated algorithms for peak analysis, background subtraction, and correction for isotopic decay.
