Table 3 The calibration range of a practical reference meter IVpe of meter Jks 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: Finally, it can be proven that the continuity from the initial indicated value is maintained.

By using this, value determination of practical irradiation equipment shall be performed by an ICRU-sphere dose equivalent rate. 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.

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. When the said energies are not a single energy, it is the effective energy. 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.

In the case of a stationary type meter, it shall be obtained promptly after installation at the place of use.


Remarks 1 Calibration of a specified secondary standard instrument and a reference meter including practical reference standard is outside of the scope of this Standard. View forum View forum without registering on UserVoice.

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. 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”.

Moreover, calculation formula of Ms may use a function formula of the measured M i and the distance. It can be performed only when the dosemeter a the same type is calibrated.

Then, an ICRU-sphere dose-equivalent practical meter shall jiz calibrated by a substitution method. The 70 ii m dose equivalent is indicated by Hi ,m.

In this case, a personal dosemeter shall be placed at the central part of the phantom and as close as possible to the phantom. The value shall be obtained by the following formula.

The purpose of calibration for 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. When y -ray irradiation equipment with the similar value setting is used independently, it shall be included in this category. Moreover, 70 ,u m dose equivalent in connection with an individual is the dose equivalent in the depth of 70 u m.


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


JIS Z English: 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.

840 3 In the case of a non-collimate y -ray b X-ray irradiation equipment shall be as specified in figure 4. Calculate the stem effect by dividing the difference of indicated value by the value obtained wdthout the shield. 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 jsi supplement made thereafter do not apply.

The record shall be maintained to enable continual confirmation.

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 calibration constant N of a dosenieter to be calibrated shall be obtained by the following formula. In addition, this dose equivalent rate is indicated by H icm.
