Attention is drawn to the possibility that some parts of this Standard may conflict with a patent right, application for a patent after opening to the public, 4801 model right or application for registration of utility model after opening to the public which have technical properties.

Figure 2 In the case of a collimate y -ray 2 In the case of a non-collimate y -ray, it shall be as specified in figure 3. In addition, this dose equivalent rate is indicated by H icm.

Express the quotient in percentage.

In this Standard, an air kerma or rate of an air kerma is expressed with an air kerma rateand an air absorbed dose or rate of an air absorbed dose is expressed with an air absorbed dose rate. Tn addition, the error of the dose-equivalent conversion factor for finding a dose-equivalent rate standard shall not be considered. When obtaining the ratio of the indicated value at the time of calibration to the initial indicated value, use half-life compensation of a radiation source.

Term search All of ProZ. When y -ray irradiation equipment with the similar value setting is used independently, it shall be included in this category. One is that a meter to be calibrated and a reference instrument specified in ISO “3 are simultaneously irradiated. Return to KudoZ list.

Next, suppose that the value would be obtained on the phantom. JIS Z English: When the said energies are not a single energy, it is the effective energy.

Figure 4 In the case of Mis irradiation 11 Radiation quality of X-rays 11,1 Measuring method of the 1st and 2nd half-value layers Under a certain tube voltage, tube current, the characteristic filter including the air spaceand added-filter conditions, a dose rate over the thickness of the filter for half- value -layer measurement of a certain single substance shall be measured. The ji constant of a meter to be calibrated shall be obtained by the following formula.

WTien y -ray irradiation equipment with the similar value setting is used independently, it shall be included in this category, I A practical reference y -ray source is a y -ray source where a reference meter determines the value of the exposure rate, the rate of an air kerma, or jks dose equivalent rate of a radiation source.

General principles, Annex B Guide to the rounding of numbers http: I think cinefill is right.

It is referred to as “calibration tables”. View Ideas submitted by the community. Eemarks 1 The dose equivalent per unit time is called “dose equivalent rate”, and jix dose equivalent or dose equivalent rate is expressed with “the dose equivalent rate ” in this Standard.

First, a meter to be calibrated is used. Round to one decimal place Entered by: If there is no corresponding energy, it shall be found by interpolation.

Iis characteristics and production methods ISO 3- X and gamma reference radiation for calibrating dose meters and doseraie meters and for determining their response as a function of photon energy — Part 3: Japanese term or phrase: Then, an attenuation-factor curve shall be created. Calculate the linearity of scale from the calibration constant. Login or register free and only takes a few minutes to participate in this question.

Use a practical meter having a definite calibration constant, and compare the value indicated after certain period of use since it was put in use, with the value indicated at the start by the same conditions of irradiation hereafter referred to as “initial indicated value”.
