## In radiation protection, the effective dose is a dose quantity defined as the sum of the tissue-equivalent doses weighted by the ICRP organ (tissue) weighting factors, wT, which takes into account the varying sensitivity of different organs and tissues to radiation.

The equivalent dose rate, based on the measured dose, can be calculated and compared with the appropriate limit of regulations 103(6) and 103(7). 2 What is The sievert (Sv) is the unit used to measure dose equivalent. For more information, see “Primer on Radiation Measurement” at the end of this document. Dose rate: The damage that is done is called the "equivalent dose" and is measured in sieverts. These were high dose, high dose-rate exposures to external radiation. where De is the equivalent dose in grays (unit of absorbed dose), and DR is the average dose rate over time. Time is given in this equation as ka (1000 years).

The unit for equivalent dose is joule per kilogram with the special dose rate; if measured values of that quantity are found to consistently exceed. The equivalent dose rate, based on the measured dose, can be calculated and compared with the appropriate limit of regulations 103(6) and 103(7). 2 What is

## A dose of one rad is equivalent to the deposition of one hundred ergs of energy in one gram of any material. Absorbed Dose Rate – Equation. The absorbed dose rate is the rate at which an absorbed dose is received. It is a measure of radiation dose intensity (or strength). The absorbed dose rate is therefore defined as:

An erg is one-ten-millionth of a joule. One hundred rad equals one Joule/kilogram (J/kg), which also equals one Gray (Gy), the standard international unit for measuring radiation dose. Suppose time is involved? Then we are talking about dose rate (or dose per unit time). An example of the units for dose rate is millirad/hour. A dose of one rad is equivalent to the deposition of one hundred ergs of energy in one gram of any material. Absorbed Dose Rate – Equation. The absorbed dose rate is the rate at which an absorbed dose is received. It is a measure of radiation dose intensity (or strength). The absorbed dose rate is therefore defined as: The dose rate is a measure of how fast a radiation dose is being received. Knowing the dose rate, allows the dose to be calculated for a period of time. Fore example, if the dose rate is found to be 0.8rem/hour, then a person working in this field for two hours would receive a 1.6rem dose. In order to distinguish penetrating and non-penetrating radiation the rate of the ambient dose equivalent at 10 mm depth H ˙ ∗ (10) of different sources and the directional dose equivalent rate at 0° and 0.07 mm depth H ˙ ′ (0.07), respectively , were measured with an end-window ionization chamber survey-meter of the BD-01 type. Dose equivalent is defined as H = D*Q, where D is the dose and Q is the quality factor taken from the table above. Dose equivalent is supposed to approximate the biological effect of different types of radiation so the Sv (or rem) is used as the unit to regulate the amount of dose an individual receives, rather than rads.

In conventional units, it is measured in mSv/sec, Sv/hr, mrem/sec or rem/hr. Since the amount of radiation exposure depends directly (linearly) on the time people 22 May 2019 The equivalent dose rate is the rate at which an equivalent dose is received. It is a measure of radiation dose intensity (or strength). 14 Dec 2019 Equivalent doses measured in industry and medicine often have The equivalent dose rate is the rate at which an equivalent dose is received. The equivalent dose is a measure of the biological effect of radiation due to several factors. The factors to take into account are as follows: The type of radiation Why are there different ways to measure a dose of radiation? When you think of a dose of medication, you think of an absolute measurement of the quantity you The equivalent dose values in Table 1 can be compared with the dose to every as measured with lithium fluoride dosimeters, were less than 14 mSv [2,18]. such a calculation cannot be used to determine the exhalation rate, since this is Radiation dose is a measure of the amount of exposure to radiation. There are three kinds of dose in radiological protection. Absorbed dose is a measureable,
