Singular surface theory is applied to study the non-uniform propagation of weak discontinuities in radiation magnetogas dynamics. The fundamental differential equations governing the growth and decay of these discontinuities are formulated and these equations are solved completely. The criteria for decay or ‘blowup’ of these discontinuities are obtained. It turns out that the weak discontinuity grows into a shock and the effect of radiation is to delay the shock formation while the electrical conductivity causes the rapid onset of shock wave.
