Vincent, Antunes and Hindmarsh have claimed that a network of cosmic strings in a scaling regime would lose energy primarily by radiation of massive particles, and that this effect could be seen even in radiation from a standing wave. We simulated such standing waves, but came to a different conclusion. We found that the radiation rate from the standing waves drops exponentially with increasing wavelength, and thus that it could not sustain a scaling network. Thus we disagree with the claim that cosmic string theories can be ruled out by overproduction of massive radiation.
