Concrete blocks with different amounts of pulverized fuel ash (PFA) substituted for cement were manufactured and tested for their compressive strength, radium contents and radon exhalation rates. It was found that PFA increased the radium contents of the concrete blocks. However, the incorporation of PFA improved the compressive strength Nike Air Force 1 Suede of the concrete blocks and decreased the radon exhalation rate. The recommended optimal percent of PFA to be substituted for cement is 15%, judging by the resulted compressive strength, radium content and radon exhalation rate. Some remarks are given on the article of A. Tidjani, entitled “Property modifications in uv irradiated polymetric track detectors”, which appeared in Nucl. Instr. and Meth. B58 (1991) 43–48. The main Air Max Thea Atomic Pink Uk thrust of the above article is the effect of uv exposure on the etching characteristics of CR-39, LR-115 type-II and CN-85. The respected author has erroneously calculated the track etching rate, Vt, used a highly inaccurate method for determination of the bulk etching rate, Vb, and misquoted references. As such, the above article is of no value at all and would mislead the Mens Nike Air Force reader.
