Moreover, 70 ,u m dose equivalent in connection with an individual is the dose equivalent in the depth of 70 u m. JIS Z Eemarks 1 The dose equivalent per unit time is called “dose equivalent rate”, and the dose equivalent or dose equivalent rate is expressed with “the dose equivalent rate ” in this Standard.
The substance used as a filter shall be of four kinds- aluminum, copper, tin, and lead. Calculate the directional characteristic from the indicated value. Login to enter a peer comment or grade. Finally, it can be proven that the continuity from the initial indicated value is maintained. Radiation characteristics and production methods ISO 3- X and gamma reference radiation for 4801 dose meters and doseraie meters and for determining their response as a function of photon energy — Part 3: It can be performed only when jie dosemeter of the same type is calibrated.
The purpose of calibration jix confirmation is to verify and confirm that the performance of a meter is maintained continually and that it is sufficiently accurate for the intended measurement which uses the said meter. The filter for half-value-layer measurement shall be of three kinds- aluminum, copper, and tin.
I think cinefill nis right. Next, suppose that the value would be obtained on the phantom. WTien y -ray irradiation equipment with the similar value setting is 88401 independently, it shall be included in this category, I A practical reference y -ray source is a y -ray source where a reference meter jiis the value of the exposure rate, the rate of an air kerma, or the dose equivalent rate of a radiation source.
Remarks 1 Calibration of a specified secondary standard instrument and a reference meter including a working reference standard is outside the scope of this Standard.
Molded stainless steel products, molded stainless steel products | TAKASAGO TEKKO K.K.
The 70 ii m dose equivalent is indicated by Hi ,m. However, when it is exchanged unavoidably the method off shall be followed.
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. But, it should have intense enough to fully verify the validity of the calibration constant of 801 meter to be calibrated.
Calculate the stem effect by dividing the difference of indicated value by the value obtained wdthout the shield. First, a meter to be calibrated is used. In that case, the indicated value at the time s calibration for confirmation shall be obtained by performing the same number of measurements. Synthesis of uncertainty shall be the square root of the sum of square of the uncertainty related to each event. Printed in Japan. Round to one decimal place Entered by: Calibration of area and personal dose meters and the measurement of their response as a function of energy and angle of incidence 3 Terms and definitions For the purposes of this Standard, the definitions given in JIS Z and JIS Z and the following definitions apply.
Moreover, the method of confirmation calibration is shown in Jos 2. Moreover, the same radiation source shall be used through the usable years of a meter. The other is that the beam monitor which monitors the output change of irradiation equipment is concurrently used. The calibration constant N of a dosenieter to be calibrated shall be obtained by the following formula. Term search Jobs Translators Clients Forums. Calibration of the personal dosemeter installed in the phantom hereafter referred to as “phantom installed personal dosemeters’O shall be performed by one method of the following- 1 In the field where a reference meter and irradiation equipment determines the practical air kerma rate standard, which is multiplied by the dose -equivalent conversion factor in order to set the ICRU slab dose-equivalent rate standard, a substitution method or an inverse square laW’ shall be used.
Term search All of ProZ. An initial indicated value shall be obtained promptly after the calibration constant is defined. When they are not single energy, it shall be effective energy. jls
You will also have access to many other tools and opportunities designed for those who have language-related jobs or are passionate about them. The coefficient of variation shall be 0.
Peer comments on this answer and responses from the answerer. By using this, value determination of practical irradiation equipment 88401 be performed by an ICRU-sphere dose equivalent rate.
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.
Grading comment Thanks everybody 4 KudoZ points were awarded for this answer. You can request verification for native languages by completing a simple application that takes only a couple of minutes.
However, calibration for confirmation may be perfbrmed continually in the following case. Moreover, 1 cm dose equivalent in connection with an individual is the dose equivalent at the depth of 1 cm from an entrance plane on the principal axis, when ICRU slab is irradiated at right angles to a principal plane with the photon of the plane parallel beam of the single direction.
If the indication of the year of publication is given to these re erred standards, only the edition of the indicated year constitutes the provision of this Standard but the revision and supplement made thereafter do not apply. Then, an attenuation-factor curve shall be created. Search the history of over billion web pages on the Internet. The relevant Minister and the Japanese Industrial Standards Committee are not responsible for identifying the patent right, application for a patent after opening to the public, utility model right or application for registration of utility model after opening to the public which have the said technical properties.
The revision responds to enforcement of the new radiation hazard prevention related statute which incorporates the new Measurement Law effective as of April, and ICRP recommendation. Late responding, but I agree on this. Vote Promote or demote ideas. The following substances shall be used as a filter, respectively- aluminum for the effective energy range of 40 keV, copper for the range of 30 keV to keV, and tin for the range 0.
