Cost: about 2 CHF/cm3 + * G4_CESIUM_IODIDE: cesium iodide, an inorganic crystal scintillator with a density of 4.51 g/cm3 and a refractive index of 1.79. radiation length about 1.9 cm. Cost: about 2 CHF/cm3 * G4_PbWO4: lead tungstate crystal (CMS ECAL). Lead tungstate has a very high density of 19.3 g/cm3 and a very short radiation length of 0.89 cm, which makes it suitable for compact and high-resolution electromagnetic calorimeters. Cost: about 3 CHF/cm3
