This invention presents a Raman spectroscopy-based method for evaluating low-dose irradiation in organoids, belonging to the field of organoid radiobiological effect evaluation / Raman spectroscopy in vitro biological detection. Given that low-dose irradiation induces relatively small biochemical changes in organoids, and that organoids themselves undergo natural maturation / metabolic drift over culture time, the irradiation effect is easily masked by "time drift." This invention constructs a time-point matched control correction evaluation framework: establishing a control baseline at each time point and extracting the net irradiation effect under this baseline, thereby achieving comparability across time points and batches. It also enables low-dose sensitive differential readout and four-quadrant genotyping output, which can be used to evaluate the differences in nucleic acid-related responses caused by different doses of irradiation at different time points, and to compare the differences in response intensity and pattern under intervention conditions such as irradiation sensitization / protection, providing a basis for subsequent screening and stratified evaluation.
