Giải phóng mặt bằng của bạn đã mở đường cho sự tham gia của bạn trong các thử nghiệm bom nguyên tử Mỹ? Munk: Vâng, quả bom phân hạch 20 kiloton trong Bikini vào năm 1946, và 17-Megaton quả bom nhiệt hạch vào năm 1951 (được gọi là Ivy Mike). | Chapter 3 Bikini 1946 and Eniwetok 1951 Hasselmann Your clearance paved the way for your participation in the American Atomic Bomb Tests Munk Yes the 20-kiloton fission bombs in Bikini in 1946 and the 17-megaton fusion bomb in 1951 called Ivy Mike . Let me talk about Bikini first. William Van Arx of Woods Hole and I were tasked to estimate the rate at which radioactive contamination would be flushed from Bikini Lagoon 13 . When viewed on Pacific maps the lagoon appeared as an insignificant speck but it was not so small when we got there. We were given 10 days to do our job. We requisitioned a Navy reconnaissance plane and rigged up a simple bombsite. Van Arx was navigator and I was bombardier. We dropped dye markers filled with a highly concentrated mixture of green hexafluoride used to locate downed fliers into the lagoon openings and the colored spots were photographed over the subsequent half tidal cycle. These spots gave a rough idea of the in and outflow. There are about ten lagoon openings and by the end of the week we had monitored nine each showing a net inflow The tenth and last channel came to our rescue with a large net outflow. The night before we had despaired as to how to report a violation to the principle of mass conservation. In spite of great care some tiny volume of the green dye would rub into my trousers. Our bunks were on USS United States Ship Allen M. Sumner DD692 . After a few days I noticed that the uniforms of the hundred or so officers and crew had taken on a greenish tinge. On the last day Captain Ciano invited Van Arx and me to his quarters for hearts-of palm hors d oeuvres. He received us in not so perfect dress-whites with the words I don t know what s wrong with the ship s laundry. Bikini was also the site of the perfect oceanographic experiment. The problem was to measure the maximum height of the waves caused by the underwater explosion Bikini Baker . One member of our team Jeff Holter purchased a case of beer emptied the contents
