... intersecting loops. There is no location of the net, but
only location on the net itself; there are no loops on space, only
loops on loops. Loops interact with particles in the same way
as, say, a photon ... elementary quantum excitation of the field, and in the
absence of charges these lines must close on themselves to
form loops. Loop quantum gravity is the mathematical

Conclusion
The problem of photon self-absorption in gamma spectrometry of environmental samples has no
simple solution because of the attenuation of photons depending on many various ... composition, sample density, and sample-detector geometry. For calculation of the
detector efficiency the absorption corrections must be then done not only to the photon self-absorption
