Method description

UHDR irradiations show healthy tissue sparing effect known as the FLASH effect. Since 2014, the FLASH effect is investigated worldwide to understand how it works and how to trigger it. The FLASH effect is defined as an in vivo effect. However, in vivo models are often expensive and time-consuming. There-fore, we wanted to use a simple, easy to manipulate but still relevant in vivo model. C. elegans was selected because of the extensive available literature and its ease of maintenance. After irradiation of C. elegans embryos, a growth delay can be observed on surviving worms.
