Further to Equation 5.4 on page 35, I neglected to say that a fourth term should be added for radon progeny. Then, inhalation intakes will comprise two terms contributing to the limiting quantity defined by the equation: committed effective dose from non-radon-progeny nuclides, and another term which is a function of the number of WLM from RnP (but which is not the committed effective dose from these nuclides).
