The theory for a spin-two massless-particle field interacting with sources is developed, in parallel with Maxwell's theory for photons interacting with charges. In the spin-two case there are two fields Eij and &, which are symmetric traceless tensors of opposite parity. Whereas a Maxwell source must be a conserved current, the spin-two source is built up in a certain way from a conserved stress-energy-momentum tensor. Polarization effects of the radiation are much the same as for electromagnetic fields; there are plane polarized, circularly polarized, and intermediate cases possible. It is suggested that a nonrelativistic test object detects the radiation through the effect of the Eij field on the object's quadrupole and octupole moments.

The classical equations of motion of a massless spinning test particle are derived as a limiting case of Mathisson-Papapetrou equations. It is shown that when a particular supplementary condition is assumed the particle follows a null geodesic and the spin is either parallel or antiparallel to the d
