Balloon-borne Instrument for Spectral Scanning of high-altitude Environments (BISSE) is a lightweight gamma-ray measurement setup that can be placed in standard weather balloons and can be retrieved after the flight. This allows multiple flights with a relatively small cost. The purpose of BISSE is to record spectral information on radiation at high altitudes. To obtain good spectral resolution with relatively small weight we use a cadmium zinc telluride (CZT) detector which has crystal dimension of 1 cm cubed. The commercially available detector is housed in a container which holds it at normal pressure at high altitudes. In this paper we present the design of our setup and show some measurement results. We also simulated the expected response of the detector at various altitudes.
