is a millionth of a millionth of a curie, what is now called a picocurie. 0.12 µµCi = 0.12 pCi = 0.44 mBq) The report estimated that by 1970, if no further atomic bomb testing was carried out, the average level would be about 1.3 picocurie (48 mBq) of strontium-90 for each gram of body calcium. The reason for the estimated rise without any further testing was attributed to the large length of time strontium-90, due to its properties, is able to stay in the stratosphere before gradually settling to earth. The report believed that what was considered a permissible level of could be reached if nuclear bomb testing continued, especially in calcium deficient soils where vegetation would absorb strontium-90 as a suitable replacement for calcium. The report made the front page of the New York Times on February 8, 1957. In June of the same year the National Academy of Sciences stated that both genetic effects and strontium-90 were potential long term hazards of nuclear weapons testing. Acid rain study Kulp was the director of the National Acid Precipitation Assessment Program, which was established by the United States Congress in 1980. In 1987 it issued an interim report stating that the effects of acid rain on the ecosphere in the U.S.A. was not particularly great. This finding was controversial and the report was not well received, especially by environmentalists, and was considered by many to be politically incorrect. Most of the United States Congress also gave the report a hostile reception. Kulp resigned as director soon after, for personal reasons. Although the reports conclusions were subsequently endorsed by the scientific community, the final report was prevented from being released by the Environmental Protection Agency until Congress had passed new rules in regards to S02 and N20 emissions in the fall of 1990. This final report, released under James Mahoney as director, differed little to the interim report. Criticism of flood geology Kulp was one of the first American fundamentalists to be trained in geology. In 1945, he joined the American Scientific Affiliation (ASA), a fellowship of scientists who are also Christians, which provided him with a forum to debate the religious implications of geology, and to expose the errors and "pseudo-science" of the likes of George McCready Price and Harry Rimmer, which he was afraid would only bring derision to orthodox Christianity. In this, he was the most important
