|Page 35; Equation 5.4:
There are a few difficulties with this equation. The left-hand side should not be given as E. Effective dose is defined elsewhere as a double-weighted sum of absorbed doses, and an estimate of E as defined in the equation cannot be called E, as this would result in more than one definition for the same quantity. Also, persoanl dose equivalent is not a true estimate of E for external exposures, as this would generally require the use of a conversion factor different from unity. Consequently, the equation would better describe a practical limiting quantity to be used as evidence of compliance with effective-dose limits. Also, the second term on the right-hand side should be designated as being applied only to non-radon-progeny nuclides. This is necessary to avoid having more than one definition for e(50) for inhalation, as exposure limitation for radon progeny is based on an epidemiological approach rather than a dosimetric one. The comments on the separate treatment of radon progeny also apply to Equation 5.8 on page 37.
