British scientists had been intimately involved in the Manhattan Project during World War II, and fully expected to be able to follow the US in testing their own nuclear weapon on American soil. Today, 65 years after the Totem I test, the effects are still being felt in South Australia and beyond.Īustralia was not the UK’s first choice of nuclear testing site. That test was one of a number conducted in the 1950s and ’60s, not by the Australian government, but by its former colonial master, the UK. It took almost three decades until the cause of the mist was acknowledged as the Totem I nuclear bomb test, as Indigenous people had been claiming for years. Others vomited and suffered from diarrhea.

In many ways they were right.Īs those exposed to it later told investigators, the black mist caused their eyes to sting and their skin to break out in rashes. But Indigenous people had a long history in the region, including Lester’s tribe.Īs the dark cloud settled over the Walatinna camp, the tribal elders attempted to ward it off, thinking it was a malevolent spirit. This was followed by a dark, ominous-looking cloud which drifted low over the ground like a slow-moving dust storm, bringing with it an unpleasant smell.Ī tiny speck in the vast South Australian outback, the area around Walatinna was regarded as “depressingly inhospitable to Europeans” by early colonizers, few of whom settled there. It also explains how the entire region of Nagasaki was affected by the radiation even though the blast destruction only spanned a few miles (Destructive Effects: Energy and Radioactivity).Yami Lester was 12 years old when the black mist came to Walatinna.Įarly on the morning of October 15, 1953, Lester heard a “big bang” in the distance. The data collected by the scientists is accurately depicted by the weather from the day and how the black rain and wind spread the radiation. The map also shows how there are amounts of plutonium surrounding the entire radius of the blast, but also similar amounts found moving east of Nagasaki. Likewise, there were amounts of plutonium found over 100 km away from the hypocenter in the Ohita region (Yoshida). The highest level of plutonium and radiation was found in the Nishiyama region, about 3 km east of the hypocenter. Their findings are shown in the Radiation Levels map shown above. According to a study in the Journal of Radioanalytical and Nuclear Chemistry, a group of scientists tested the amount of 239+240 Pu in soil levels in Nagasaki and the surrounding cities on the island. With the rain and the wind moving the cloud east southeast, the radiation began to spread away from the hypocenter and began to cause more damage than expected. While the concentration of plutonium varied, it still contained radiation. However, the rain also contained amounts of 239+240Pu(plutonium and uranium) from the blast. The cloud began to rain, but it wasn't normal rain.The water was mixed with the dust and debris and was called “black rain”. The cloud was moving east-southeasterly at a speed of 3 m/s (or approximately 7 mph) (Yoshida).

As these all mixed after the blasts, a cumulonimbus cloud was created.

After the explosion, there were massive fires, dust and debris, and a handful of chemicals in the air. However, this is not what occurred in Hiroshima and Nagasaki. The amount of radiation would then be less and less as you moved further along the radius of the blast. The amount of radiation near the hypocenter of the blast should be where it is highest. The assumed flow of radiation would be similar to the blast radius from the bombs.
