What guidelines were used by miller and urey when they constructed their experiment?

Guidelines used by Miller and Urey:

In 1952, Stanley Miller with the support of Harold Urey conducted the classic experiment investigating the original evolution of life from chemical substances. (abiologically)

Miller and Urey conducted experiments by setting up an apparatus trying to provide the proof that organic compounds can exist from inorganic compounds. His apparatus had conditions nearly similar to the time of life started and by the flow of electricity which had water , methane , ammonia , and hydrogen obtaining various organic molecules.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
