发光年龄的不确定性至少为4- 5%，主要是由于剂量率（转换因子）和等效剂量（源校准）估计的系统误差。在大多数情况下，由于随机误差（例如，等效剂量的传播）或假设的不确定性（例如，含水量波动，埋葬历史），不确定性会更高。年代测定可能在几十年到大约50万年的广泛年龄范围内进行，尽管在这个范围的极端情况下，不确定性通常相对较大。
Luminescence ages have an uncertainty of at least 4–5%, mainly due to systematic errors in both dose rate (conversion factors) and equivalent dose (source calibration) estimation. In most cases, the uncertainty will be higher, due to random errors (eg, spread in equivalent doses) or uncertainty in assumptions (eg, water content fluctuations, burial history). Dating is possible for a wide age range of a few decades to about half a million years, although uncertainties are usually relatively large toward the extremes of this range.
