The RS 2400's cylindrical X-ray source yields dose rates high enough to allow the irradiator to replace widely used gamma irradiators. Except for the leftmost 5 cm, beam uniformity is within 10% at the tube surface. At maximum operating parameters, the beam has HVL(1)=13.66 mm aluminum, HC=0.47, and hv(eq)=88.5 keV. Maximum dose rates to tissue are 65 Gy min(-1)+/-3.1% at tube surface, 37 Gy min(-1)+/-3.1% at center of canisters, 14.1 Gy min(-1)+/-6.5% for thin-shelled oysters, and 12.3 Gy min(-1)+/-6.2% for thick-shelled oysters.
RS 2400的圆柱形X射线源产生的剂量率足够高，使得该辐照器能够取代广泛使用的伽马辐照器。除了最左边5厘米外，在管表面处束流均匀性在10%以内。在最大运行参数下，该束流的半价层（HVL(1)）为13.66毫米铝，质能转换系数（HC）为0.47，等效光子能量（hv(eq)）为88.5千电子伏。在管表面处对组织的最大剂量率为65戈瑞每分钟（Gy min(-1)）±3.1%，在罐中心为37 Gy min(-1)±3.1%，对于薄壳牡蛎为14.1 Gy min(-1)±6.5%，对于厚壳牡蛎为12.3 Gy min(-1)±6.2%。
