YSO vs. NaI:

• NaI is easily deliquesced
• NaI is toxic
• NaI is fragile
• NaI needs to be sealed in aluminum alloy to prevent deliquescing and damage, increasing the size and weight of the detector

YSO vs. Ion Chamber:

• Ion chamber needs to be large in order to have good detection capability
• At the same size, YSO has much higher sensitivity
• Ion chamber is extremely sensitive to the environment (i.e. humidity, temperature, air pressure)
