In each male, the following testicular lesions were scored: (1) hemocytic infiltration of the gonadal acini and phagocytosis of spermatogenic cells, (2) hemocytic infiltration of interacinal connective tissue, (3) aggregations of hemocytes under the mantle epithelium, and (4) occurrence of brown cells.
For example: a long exposure refers to a single, protracted shutter cycle to capture enough low-intensity light, whereas a multiple exposure involves a series of relatively brief shutter cycles; effectively layering a series of photographs in one image.
Absorbed dose and duration of exposure. The absorbed dose of radiation is measured in a unit called a gray (Gy). Diagnostic tests that use radiation, such as an X-ray, result in a small dose of radiation â typically well below 0.1 Gy â focused on a few organs or small amount of tissue.
