Does any one has information on chemical toxicity (Y-axis) and its relation to chemicals dose (X-axis). Can we apply LNT model or any Threshold model?

Does plot of chemical toxicity (Y-axis) and its relation to dose (X-axis) is linear obeying LNT model or we have to apply Threshold model for doses response of chemicals. Information on any...

What should be the depth (d-mm) of measurement for dose equivalent Hp(d) for high energy photons (E>10 MeV) instead of 10 mm used presently?

Presently Hp(10) is surrogate to Effective dose, But this holds for lower energy photons (x-rays, photons from Cs or Co etc.) say having E upto 3 MeV and is not conservative estimate of Effective...
