  • NOTE: The data for session A were taken from the fourth column of Table 1 (volunteer 8 participated only in session A and was therefore not included). For session B, the exposure time was 50% of that in session A. For session C, the upper part of the solarium was covered resulting in 50% of the body being exposed. Sessions A and B were repeated once.
