Rain and Nuclear Detonations

New documents released as part of the Merlin database expose the AWE's knowledge and the restriction of information to protect their narrative. In this blog, we concentrate on a letter sent from the AWE to Dr C J Morgan at the Ministry of Defence. It is dated 4th August 1992.

The letter is in response to a Rainout Report HRP/RAIN/92/P1 and contains 8 paragraphs.

So the rain could be contaminated, and the MOD are aware of this fact, yet they have always denied it.

Science knows that if rain forms within the radioactive cloud or above it, then the contamination will be carried down to the ground.

The admission that rain can be induced by detonations in theory.

Rain in the immediate vicinity shortly after the detonation is likely to be contaminated.

Because the personnel were over 10km away for KT and over 35Km for MT detonations, the personnel should be safe, but there is no confirmation of this.

Grapple Z1 showed radioactivity in the rain, but the rain was minuscule, and the errors were probably very large. But rain was only monitored at ONE location at Christmas Island. Why only at one location?

The AWE knew that rain could be induced by a detonation, and should be STUDIOUSLY avoided in unclassified documentation. Don't tell anyone, especially the personnel.

An admission that Totem 2 was much larger than the 6 KT recorded; it was actually nearer 10 KT.

Conclusion
This document shows that the AWE knew that nuclear detonations could cause rain; they knew that it rained at certain tests and that quoted yields were higher than quoted. But instead of informing the affected personnel or informing Parliament, they kept it secret.
This is one of thousands of documents that show the AWE kept information secret to maintain the narrative that the tests were safe and the personnel were in no danger. The UK Government must act upon this information; they must now acknowledge that the personnel involved in the tests were put in harm's way and that there was a risk.
With the meteorological information that has been collated and the admission that fallout fell on occupied areas of Christmas Island, the evidence is increasing. The detonation caused the rain, and the radioactive fallout landed over the island. The background levels increased. Yet the UK Government insist that the background levels never increased. We know this is incorrect, and the record must be corrected.
In Joe Pasquini's book 'The Curse of the Nuclear Cloud Flyer', he reported the rain that fell on his aircraft. No one took him seriously, but he was right.
