西韦特单位 meaning in English
sievert unit
Examples
- It is therefore completely impossible to avoid ionising radiation altogether . the average background radiation as about 2 msv per year
换言之，我们不可能完全避免电离辐射，每年接触到的本底辐照量平均为两毫西韦特单位。 - A special case exists for pregnant workers because of the potential for radiation to damage the developing foetus . after the pregnancy is declared , the dose limit is 1 msv for the rest of the pregnancy
怀孕工人的情况亦有所不同，由于辐射有可能对成长中的胎儿造成损害，故一旦怀孕，在怀孕期间的吸收剂量便不能超过一个毫西韦特单位。 - Workers whose annual dose is likely to exceed 6 msv are required to be classified as radiation workers . this requires that their exposure be measured and regularly monitored and that they be subject to periodic medical examinations
全年吸收剂量有可能超过六个毫西韦特单位的人士，便被列为在辐射下工作的人士，需接受辐射接触量的量度和定期监察，并需定期进行身体检验。 - For the general public , i . e . those persons who do not have contact with radiation as part of their work , the recommended limit is 1 msv per year . for persons whose work requires that they have contact with radiation , the limit is 20 msv per year
一般而言，工作时不需经常接触到辐射的人士，建议上限为每年一个毫西韦特单位因工作关系经常接触辐射的人士，上限则为每年二十个毫西韦特单位。 - Particulate radiation is generally more damaging in biological systems than electromagnetic . the unit is the sievert , but as it is a very large unit the millisievert which is a thousandth of a sievert is more common as is the microsievert , a millionth of a sievert
至于量度辐照量的单位为西韦特sievert ，但西韦特是一个大单位，故此一般以其千分之一即毫西韦特单位msv或以百万分之一即微西韦特单位msv来量度。
