In photographs of the 180-liter xenon bubble chamber we have found 7 radiative {ital K}{sup +}{r arrow}{pi}{sup +}{pi}{sup +}{pi}{minus}{gamma}-decay events for which in each event the {gamma} quantum is registered directly, and 28,168 {ital K}{sup +}{r arrow}{pi}{sup +}{pi}{sup +}{pi}{minus}-decay events. In the {gamma}-quantum energy region {gt}5 MeV in the rest system of the {ital K}{sup +} meson the ratio {Gamma}({ital K}{sup +}{r arrow}{pi}{sup +}{pi}{sup +}{pi}{minus}{gamma})/{Gamma}({ital K}{sup +}{r arrow}{pi}{sup +}{pi}{sup +}{pi}{minus}) has been measured and found to be (1.97{plus minus}0.85){times}10{sup {minus}3} which corresponds to the ratio {Gamma}({ital K}{sup +}{r arrow}{pi}{sup +}{pi}{sup +}{pi}{minus}{gamma})/{Gamma}({ital K}{sup +}{r arrow}all)=(1.1{plus minus}0.48){times}10{sup {minus}4}.
