\(h_{tg}.f=\psi_{tg}+\Phi_{tg}\)
where \(\Phi_{tg}\) is the work density function for work done against an opposing gravity field.
Photons beyond the threshold frequency, \(f\) will be able to eject gravity particles from the radioactive material, both positive and negative particles alike. Such photons exist in \(t_g\) time dimension, in order to interact with gravity particles.
Two types of photons for two types of gravity particles.
