RadChemDosi™ Cell Survival Assay Kit contains enough reagents for 100 test if 1 ml is used for irradiation. RadChemDosi™ is sensitive to measure the dose rate as low as 2.5Gy/min at various positions in a Cesium irradiator chamber. In addition to calibrating the dose rate at each position in a radiation chamber periodically, it can also be used to measure the dose rate in each well of a 6 and 24 wells plate.
