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. 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. Moreover, the practical exposure rate standard is multiplied by the air absorbed dose conversion g factor in order to set vip the filed of the practical air absorbed dose rate standard.

Finally, it can be proven that the continuity from the initial indicated value is maintained. Review native language verification applications submitted by your peers. Consequently JIS Z An initial indicated value shall be obtained promptly after the calibration constant is defined.

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. Peer comments on this answer and responses from the answerer agree. When energy is 3 Jiz or over, deviation from electronic equilibrium makes it impossible to accurately determine an exposure.

Grading comment Thanks everybody.

Table 3 The calibration range of a practical reference meter IVpe of meter Scale Energy Digital type One point, near the centre of each decade in a required mesurement range — As for a practical reference meter, one point of keV i: You can request verification for native languages by completing a simple application that nis only a couple of minutes. The calibration constant N of a dosenieter to be calibrated shall be obtained by the following formula.


When the said energies are not a single energy, it is the effective energy. Moreover, the method of confirmation calibration is shown in Annex 2. As for the quality of the material of the substance used for the filter, the purity shall be Remarks 1 Because the calibration distance is 2 m or over, the calibration distance may be measured on the surface of the phantom.

Unless otherwise specified, no part of this pubhcation may bo reproduced or utihzed in any form or by any means, electronic or mechanicat including photocopying and microfilm, without permission in writing from the publisher.

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. One is that a meter to be calibrated and a reference instrument specified in ISO “3 are simultaneously irradiated.

Round to one decimal place. Not trying jia be difficult, but did you try to find JIS Z ? A long dashed double-short dashed line shows the relation to a practical ICRU slab dose- equivalent rate standard.

The calibration constant of a meter to be calibrated shall be obtained by the following formula. 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. Moreover, in the class of practical reference meter, there are an exposure or an air kerma practical reference meter, and a dose-equivalent practical reference meter.

Synthesis of jos shall be the square root of the sum of square of the uncertainty related to each event. The KudoZ network provides a framework for translators and others to assist each other with translations or explanations of terms and short phrases.


Return to KudoZ list. 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 jid 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.

Moreover, the same radiation source shall be used through the usable years of a meter. It shall also be based on the practical dose-equivalent rate standard whose value is decided by the practical dose -equivalent rate standard, as well as the calibration for confirmation. When they are not single energy, it shall be effective energy. Subtract its minimum from its maximum and divide the difference by its minimum. English PRO pts in category: Calibration of a dose-equivalent practical meter shall be based on the dose-equivalent rate standard which is obtained by multiplying the practical air kerma rate standard by the dose-equivalent conversion factor.

The coefficient of variation shall be 0. The contents shall be as follows- a The name, model, serial number, calibration date; calibration personnel and calibration constant of a meter to be calibrated. Moreover, calculation formula of Ms may use a function formula of the measured M i and the distance. 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.

It is referred to as “calibration tables”.
