An apparatus has been designed for determining the surface area of highly radioactive coarse particles. The system uses krypton as the adsorbate and a thermistor manometer to measure pressures. Measurements have been made on samples with areas as low as 50 cm2. The design, construction, and precision of the system are discussed.
