Mathematical Formulation: Inhalation Dose<br />
• Inhalation Dose<br />
– Where<br />
– T = Exposure period [h.a-1 ]<br />
– SA = Specific activity of U-238 or Th-232 in the waste rock [Bq.g-1 ]<br />
– M = Gravimetric airborne activity [mg.m-3 ]<br />
– BR = Breathing rate of exposed persons [m3 .h-1 ]<br />
– DCInh = Inhalation DC for uranium or thorium [Sv.Bq-1 ]<br />
– Inhalation dose coefficients for the uranium and thorium series with all nuclides<br />
in secular equilibrium were calculated from nuclide coefficients selected from<br />
the IAEA BSS for dust with an AMAD of 5 μm.
