Still, their fossilization required a suite of factors: a slow rate of decay of soft tissues, little scavenging by other animals, a lack of swift currents and waves to jumble and carry away small bones, and fairly rapid burial.
The variant rate of decay rate is zero within thhe accuracy errors.
The story begins, in a sense, in classrooms around the world, where students are taught that the rate of decay of a specific radioactive material is a constant.
The actual rate of decay may be somewhat greater or less than this expected rate.
This effect can be measured in either the time domain by observing the rate of decay of voltage or in the frequency domain by measuring phase shifts between sinusoidal currents and voltages.
That fall into the cave happened 1.977 million years ago, according to dating based on the rate of decay of uranium in the rock layer that holds the fossils.
Element 43 has a very fast rate of decay.
This altered the propagation of GPS signals and slowed the rate of decay of space debris in low Earth orbit.
No one knows how neutrinos could interact with radioactive materials to change their rate of decay.
