Background: The sterile male release technique (SMRT) is a useful method applied for controlling invasive and pest species. However, the use of X-rays can lead to negative effects on the survival and health conditions of sterilized males.
Results: This study was set up to evaluate the functional integrity of physiological, morphological and behavioural responses in males of the red swamp crayfish, Procambarus clarkii (Girard, 1852), exposed to a dose of 40 Gy of ionizing radiation.
