### Equivalent dose - Nuclear radiation - National 5 Physics

• $Equivalent\,dose = Absorbed\,dose \times Radiation\,weighting\,factor$ $H = D \times {W_R}$ Equivalent Dose ($$H$$) is measured in Sieverts \((Sv)\
• Dose equivalent (or effective dose) is calculated as follows: Dose equivalent= (Absorbed dose)× (weighting factor or RBE). Recommended weighting factors are approximately 1 for x-rays, gamma rays, beta particles, and electrons, and 20 for conventional neutrons (>0.1-2 MeV), protons, alpha particles and charged particles of unknown energy
• In the US, three different equivalent doses are typically reported: deep-dose equivalent, (DDE) shallow dose equivalent, (SDE) eye dose equivalent

Equivalent dose is based on the absorbed dose to an organ, adjusted to account for the effectiveness of the type of radiation. Equivalent dose is given the symbol H T . The SI unit of H T is the sievert (Sv) or but rem (roentgen equivalent man) is still commonly used ( 1 Sv = 100 rem ) That is, equivalent doses are 1 mSv for all organs and tissues. To calculate effective doses, the equivalent doses for individual tissues are multiplied by their respective tissue weighting factors and the products are summed Use this simple atomic physics calculator to calculate equivalent dose absorbed by tissue for radiological protection online Equivalent dose (H T) is calculated by multiplying the absorbed dose to the organ or tissue (D T) with the radiation weighting factor, w R. This factor is dependent on the type and energy of the incident radiation Equivalent dose is expressed in millisieverts (mSv) to an organ. Effective Dose Effective dose is calculated for the whole body. It is the addition of equivalent doses to all organs, each adjusted to account for the sensitivity of the organ to radiation. Effective dose is expressed in millisieverts (mSv). More Details [see more/less

weighted dose quantity HT is redeﬁned as the equivalent dose ~as opposed to the dose equivalent! HT5SwRŁDT,R, where wR is the radiation weighting coefﬁcient,DT,R is the average absorbed dose to tissue T, and HT ~equivalent dose! is the summation over all radiation types and energies of the product wRŁDT,R. For x rays, the value of wR is 1. Thus th To calculate exposure to the whole body or to multiple tissues or organs, the effective dose is calculated by multiplying the equivalent doses by the weighting factor for each tissue or organ, and summing across tissues and organs. ICRP have recommended tissue and organ weighting factors for various types and energies of radiation (ICRP 103, 2007) Equivalent dose is given the symbol H T. The SI unit of HT is the sievert (Sv) or but rem (roentgen equivalent man) is still commonly used ( 1 Sv = 100 rem ). Unit of sievert was named after the Swedish scientist Rolf Sievert, who did a lot of the early work on dosimetry in radiation therapy. Equivalent Dose Rat Biologically equivalent doses are calculated in 2-Gy equivalents using the EQD 2 equation. An equivalent total dose in 2-Gy fractions (EQD 2) can be found for any BED by dividing it by the RE for 2-Gy fractions, using the appropriate α/β ratio. The variables used are: Irradiation duration - can be less than a few minutes or more than a few minutes

### Equivalent Dose - an overview ScienceDirect Topic

• Equivalent dose is measured using the sievert but rem is still commonly used (1 Sv = 100 rem). Equivalent dose ( HT) is calculated by multiplying the absorbed dose to the organ or tissue ( DT) with the radiation weighting factor, wR. This factor is dependant on the type and energy of the incident radiation
• The biologically effective dose and equivalent dose in 2Gy calculators are based on the Linear Quadratic Model. As with any model there are limitations including the lack of a time factor and its applicability for low doses per fraction (1.2Gy). The doses are calculated as a guideline to allow conversion and comparability of different.

• So in a 5mL dose you would have the equivalent of 3.5g of fresh chickweed (i.e. 5mL x 1/1.4). If you wanted to look at dry herb equivalence then you need to do more processing and calculations. This involves taking a small sample of fresh chickweed, then you weigh it, and then heat it in a low oven until it is full dry The Total effective dose equivalent (TEDE) is a radiation dosimetry quantity defined by the US Nuclear Regulatory Commission to monitor and control human exposure to ionizing radiation.It is defined differently in the NRC regulations and NRC glossary. According to the regulations, it is the sum of effective dose equivalent from external exposure and committed effective dose equivalent from. The calculation of the committed effective dose equivalent (CEDE) begins with the determination of the equivalent dose, H T, to a tissue or organ, T, listed in Table A.2 below by using the equation: H — T = ∑ R D — T , R · w —

Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value. For example, 2/4 and 3/6 are equivalent fractions, because they both are equal to the ½. A fraction is a part of a whole. Equivalent fractions represent the same proportion of the whole Equivalent Dose • Biologically equivalent doses are calculated in 2 -Gy equivalents using the EQD2 equation • Cumulative: brachytherapy dose added to the dose from external beam therapy Bentzen et al., Radiother Oncol 105: 266-268, 2012 .

dose. The conventional unit for absorbed dose is the Rad, the international unit is called the Gray (Gy). EQUIVALENT DOSE The absorbed dose quantifies the amount of energy transferred to a volume of material, but it does not reflect the biological damage that potentially occurred. Because of th It does this by using, as a common denominator, an estimate of the levodopa equivalent dose (LED). The LED is the amount of levodopa (taken with carbidopa) that has a similar effect as the drug taken. Adding together all the LEDs in a day gives the levodopa equivalent daily dose (LEDD) To convert 1.8g to the equivalent milligram dose, it must be multiplied by 1,000 to get 1,800mg. Other complex calculations can give the prescribing dose for dose/kg/min. There are formulas that can help with these calculations to reduce the number of steps needed in converting dosages into the volume required per hour (Fig 3)
