-lines 717-719 (37) - Consider to change “ .. with the central consideration being optminisation process below appropriate dose restrictions.” In “ .. with the central consideration being optminisation process a requirement below appropriate dose restrictions.”
-lines 734-743 (in 39) – Even if this draft document is more focused on existing exposure situations, consider to maintain the order of presentation, as in ICRP 103 and other publications, as: -planned, emergency and existing exposure situations
-lines 756-757 (in 41) - Consider to continue to use, as in ICRP 103 and in the glossary of this draft, for the three categories of exposures: occupational, public and medical exposure of patients.
-lines 7563-764 (in 41) – Consider to change in “Public exposure encompasses all exposure of the public other than occupational exposures and medical exposures of patients.”
-line 779-780 (in 43) – Consider to change “…justification principle is applied in making the decision as to whether to take action to reduce exposure and avert further additional ones “ in “…justification principle is applied in making the decision as to whether to take action to reduce exposure and avert further exposure“
-line 804-811 (in 47) – By talking about optimisation it is written “ …. As low as reasonably achievable (ALARA) below appropriate individual dose criteria, taking into account economic and societal factors. “ ….. “the Commission recommends using individual dose criteria (reference levels and dose contraints) in the optimisation process (Paragraph 226 of Publication 103). “. Moreover in line 339-340 (in glossary) we have : “…(ALALRA) below the appropriate dose criteria (constraints or reference level), ..”. The suggestion: -since the wording dose criteria and individual dose criteria in not reported in ICRP 103, the suggestion is to be consistent with the used wording in this draft, and moreover to take the opportunity to introduce in the glossary “dose criteria” or “individual dose criteria” may be considering also, more in general to include also the ‘dose limits’.
-line 813-815 (in 48) – Consider to change “ … judged to be inappropriate to allow exposure occur ..” as “…judged to be inappropriate to plan to allow exposure occur ..” in consistence with what written in ICRP 103 and in this draft glossary and moreover to change “protective actions should be implemented” as “protective actions should be planned and optimised” as in ICRP 103 (234) and if you want also specifically “ should be implemented” but to cite “optimised” should be useful.
- line 844-848 – Consider to move “taking into account economic and social factors” from line 846 to 848 after “as low as reasonably achievable”
-line 927-927 – Thank you for the recommendation that general imformation about cosmic radiation should be made available for all passengers for example through the airlines’ websites, it will be very useful.
- Frequent flyers-The definition of frequent flyers as in the glossary, and then introduced in (61), is very basic and really the registration in a frequent flyer programme could have or not have an indicative value. In (62) the Commission encourages who may be concerned by their exposure to use dose calculators and to adapt their flight frequency as they feel the need. In this context, since the point on the attention to the flyer radiation exposure is already introduced, a tentative value of frequency in relation frequent flyers, and moreover of the frequency which result in exposures comparable to aircraft crew could be proposed in (62) and in (63).
-4.2.3 Aircraft crew – Consider to add, for a more comprehensive approach, a sentence on dose to the lens of the eye similar to that in IAEA 1731, 2013 (Implications for Occupational Radiation Protection on the New Dose Limit for the Lens of the Eye) by remebering again that in existing exposure sitation the dose limits do not apply and that due to the homogeneity of the radiation field the dose to the lens of the eye can be assumed to be similar to effective dose .
