Stabilization. A room-temperature plastic scintillation detector immersed in 29°C water displayed a stable response over 40 minutes, from the first measurement at 50 seconds after immersion (dashed lines indicate ±1% from the average response). A slight upward trend owing to a small decrease in the temperature of the water over the 40 minutes was observed. Identical measurements in air confirmed that the plastic scintillation detector was stable under normal conditions.
