西韋特單位
英文
sievert unit-
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
全年吸收劑量有可能超過六個毫西韋特單位的人士，便被列為在輻射下工作的人士，需接受輻射接觸量的量度和定期監察，並需定期進行身體檢驗。It is therefore completely impossible to avoid ionising radiation altogether. the average background radiation as about 2 msv per year
換言之，我們不可能完全避免電離輻射，每年接觸到的本底輻照量平均為兩毫西韋特單位。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，工作時不需經常接觸到輻射的人士，建議上限為每年一個毫西韋特單位因工作關系經常接觸輻射的人士，上限則為每年二十個毫西韋特單位。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
至於量度輻照量的單位為西韋特sievert ，但西韋特是一個大單位，故此一般以其千分之一即毫西韋特單位msv或以百萬分之一即微西韋特單位msv來量度。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
懷孕工人的情況亦有所不同，由於輻射有可能對成長中的胎兒造成損害，故一旦懷孕，在懷孕期間的吸收劑量便不能超過一個毫西韋特單位。分享友人
