tolerance dose
Technical term used in radiology and radiation protection for the maximum dose of radiation that can be received without significant harm.
The tolerance dose for radiation workers is stipulated by law.
許容線量 (permissible dose) is a broader term for any allowed dose, while 耐容線量 specifically refers to the dose that can be tolerated without harm.
Compound of 耐容 (tolerance) and 線量 (radiation dose). The exact historical derivation is uncertain; the term is a modern technical coinage.
