20 blood samples of two age groups (10 volunteers 16-20 years old, 10 volunteers 50-65 years old) were stimulated with PHA, exposed to three different specific absorption rates and investigated. Positive controls were performed for every blood sample and each test. The study was a collaboration of six independent institutes. Genotoxic tests were conducted by one institute and evaluated by three different institutes. Three institutes were responsible for blood collection and exposure, exposure design, and statistical analysis.
eight waveguides arranged in four separately controlled exposureunits (containing 72 culture dishes of 35 mm in diameter); in each waveguide, one dish holder with 9 cell culture dishes; each exposure unit consisted of a power splitter connecting two single-mode cavities for 1.8 GHz that are based on R18 waveguides; the system was capable of driving four different power levels in parallel that are randomly assigned to the four exposureunits; two waveguides (18 dishes) per SAR; eight waveguides mounted on an aluminium rack; system placed in an incubator with constant environmental conditions
