What is Hp(10) and Hp(0.07)?

Hp(10) and Hp(0.07) are personal dose equivalents, which represent the probability of stochastic health effects from radiation. Hp(10) is the deep dose equivalent. It is the equivalent dose at 10 mm below a specified point of the body. Hp(0.07) is the shallow dose equivalent, also referred to as skin dose equivalent or surface dose equivalent. It is the equivalent dose at 0.07 mm below the surface of the body. Currently, RadTarge II measures Hp(10). The option to switch between Hp(10) and Hp(0.07) will be added to future iterations of RadTarge II.

What are the advantages of YSO?

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)
