Brief
The article simulates and analyzes the minimum detectable activity concentration of a scintillating fiber array detector for low-level radioactivity measurement in water by evaluating its detection efficiency for beta particles and background counting rate from sources like cosmic rays and shielding material.
Summary
This paper uses Monte Carlo simulations to evaluate a scintillating fiber array detector designed for online measurement of low-level radioactivity in water. The study determined the detector's minimum detectable activity concentration by analyzing its beta particle detection efficiency and background count rate from sources like cosmic rays, finding it can reach 1.0 Bq/L in 6 minutes and 0.457 Bq/L in 30 minutes, demonstrating its potential for rapid and sensitive water quality monitoring.
