Abstract
A neutron irradiation setup for in vivo activation analysis was characterized to optimize its spectrum measurements. In order to have a reliable spectrum, some shields and filters were defined to eliminate as much background possible. Since there were different types of background sources, different states were studied and necessary shields were employed to optimize the spectrum. To use a neutron shield, boron carbide layers (3 cm) around 3 9 3 in. sodium iodine detectors were employed. To prevent c-ray background, bismuth (2 cm) is used under the detectors.
