The samples RATE tested were from a borehole sample retrieved in 1974 with no statement made as to the storage or collection conditions of the samples.
In a statement on page 72, the report states that "[t]hey were taken from a depth of 750 meters, where the temperature was measured at a constant 96°C" (De Young, 2005).

It is much easier to use an element that has very little ability to migrate than one that has a great ability to move in and out of rock.The major problem with using Helium as a measure of age is that alpha decay always releases a Lead, it is relatively abundant in Earth's crust and is constantly escaping through the crust into the atmosphere.While the RATE project can be commended for trying to use scientific methods for proving a young Earth, there are too many questions regarding its execution and too much ability for a false date to be calculated from the Helium amounts in the rock samples.Excess Helium in rocks may be a genuine mystery, but all possible explanations must be investigated before a true understanding can emerge.
