The Delayed Effects of Acute Radiation Exposure (DEARE) take months and years to develop and typically manifest as fibrosis. Epistem's extensive knowledge of the effect of radiation exposure has been applied to in vivo models of GI-DEARE. In the intestine these late effects are seen as changes in GI pathology (crypt and villus size and number, and levels of fibrosis).

DEARE Model Description

X-ray irradiation is performed with bone marrow shielding where required. Full dosimetry of the 320kV source is also performed for each study run.
