dose conversion factorとは 意味・読み方・使い方

Case1 is the case approaching the Minimal Anticipated Biological Effect Level (MABEL) and Case2 differs from the conventional use of the No Observed Adverse Effect Level (NOAEL). When calculating the first-in-human dose, the majority of cases will fall into the following categories: cases in which the dose per unit body weight will be obtained from the MABEL or NOAEL (mg/kg) and will then be divided by a safety factor; cases in which the dose (mg/m2) per unit body surface area (m2) will be used for conversion to the Human Equivalent Dose (HED) to ensure equivalence between study animals and human subjects.例文帳に追加

事例１は NOAELを設定根拠した事例，事例２は MABEL を設定根拠にした事例を示しますが，これらの事例のように体重あたりの投与量として得られた MABELまたは NOAEL（mg/kg）の他 - 厚生労働省

The sum (area of dose) of values of the dose of radiation emitted by a specific nuclide obtained under the ground is divided by a conversion factor which assumes a different value depending on the use of land in an area under investigation, whereby the dose of radiation emitted by the nuclide is determined.例文帳に追加

地中で得られた特定核種による放射線量の値の和（放射線量の面積）を調査地域の土地利用形態によって異なる値である換算係数で割ることにより、その核種の放射能量を得る。 - 特許庁

More specifically, the sum of values of the dose of radiation emitted by the specific nuclide measured in a hole with a depth of about 50 cm (about 2.5 cm in diameter) under the ground is divided by a conversion factor for data on the use of land in the area under investigation, whereby the dose of radiation in that site is determined.例文帳に追加

具体的には、地中５０ｃｍ程度の深さの穴（直径２．５ｃｍ程度）の中で測定された特定核種の放射線量の値の和を調査地域の土地利用データ（森林、耕作地、未耕地に分類）の換算係数で割ることにより、その場所の放射能量を得る。 - 特許庁
