Impact of beta radiation on the strength of Steatoda triangulosa spider silk
- 68 Downloads
Silk from the spider Steatoda triangulosa is harvested, and samples are subjected to various doses of beta radiation using a scanning electron microscope (SEM). Irradiated and unirradiated samples are destructively tested to determine the stress–strain characteristics. From these data, the strength of the irradiated silk is determined as a function of dose.
