WebUsing 22Na as an analog for 40K, our results suggest that the pressure effect for 40K, combined with the opposing effects of high temperatures, will have little, discernible effect on the heat production in the deep Earth as our predicted changes are smaller than the uncertainties in the total decay constant for 40K. WebDecay constant: probability of decay Half life: time for the activity to be reduced to 50% Time dependent change . from configuration 1 (radioactive nucleus) To configuration 2 (decay product, daughter) Activity corresponds to the number of sand particles dripping through hole Decay constant is associated with the size of the hole
