| equivalent dose A quantity used in radiation protection, expressing all radiation on a common scale for calculating the effective absorbed dose. The unit of dose equivalent is the rem. which is numerically equal to the absorbed dose in rads multiplied by certain modifying factors such as the quality factor, the distribution factor, etc. | 等效剂量 (放射保护中使用的量，为表达放射量，方便计算有效吸收剂量提供的统一度量。单位是rem。数量上等于1rad辐射下的吸收剂量乘以某些修正因子，例如质量因子，分布因子等。) |
| equivalent zero emission standard | 等效零排放标准 |
| noise equivalent delta temperature | 噪声等效温差 |
| population equivalent of industrial wastewater | 工业废水人口当量 |
