We assume that the cascade is one-dimensional, and we find that this approximation is justified in the present work for thermal radiation with temperature less than 10&lt;SUP&gt;-3&lt;/SUP&gt; mc&lt;SUP&gt;2&lt;/SUP&gt;. Results are obtained for both monoenergetic and power-law primary spectra, and for a variety of path lengths. We find that triplet production is particularly important in electron-photon cascades through thermal radiation when the primary energy exceeds 10&lt;SUP&gt;5&lt;/SUP&gt;m&lt;SUP&gt;2&lt;/SUP&gt;c&lt;SUP&gt;4&lt;/SUP&gt;/kT for propagation over small path lengths. The importance of triplet production decreases as the path length increases, and it has no effect on saturated cascades.</style></abstract></record></records></xml>
