With respect to table 3 I suggest that the Commission makes clear that it should read: 1. Red bone marrow instead of Bone marrow, and 2. colon wall, stomach wall, bladder wall, oesophagus wall,etc. The Commission should make a clear statement about the use of effective dose for medical examinations. It became common practise to calculate effective dose for all kinds of radiological examinations without realizing if the quantity calculated really makes sense for the patients examined.
