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

The contents shall be as follows- In addition, method to round numbers shall be as specified in JIS Z Remarks 1 Calibration of a specified secondary jid instrument and a reference meter including practical reference standard is outside of the scope of this Mis. Not trying to be difficult, but did you try to find JIS Z ? Calculate the reproducibility of response from the calibration constant. Return to KudoZ list. The normative references without the indication of the year of coming into effect apply only to the most recent editions including amendments.

An initial indicated value shall be obtained promptly after the calibration constant is defined.

Participation is free and the site has a strict confidentiality policy. Secondly the relation of indicated value against both is obtained with sufficient accuracy with coefficients of variation within 0.

Close and don’t show again Close. In this Standard, an air absorbed dose practical meter is included in an air kerma practical meter. However, when it is exchanged unavoidably the method off shall be followed.

The substance used as a filter shall be of four kinds- aluminum, copper, tin, and lead. 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.


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

But, it should have intense enough to fully verify the validity of the calibration constant of a meter to be calibrated. 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.

Next, jix that the value would be obtained on the jiss. 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”.

Synthesis of uncertainty shall be the square root of the sum of square of the uncertainty related to each event. The ionization chamber shall have the wall thickness or entrance window thickness and meet the performance indicated in table 1, depending on each energy range used.

However, calibration for confirmation may be perfbrmed continually in the following case.

The revision responds jia enforcement of the new radiation hazard prevention related statute which incorporates the new Measurement Law effective as of April, and ICRP recommendation.

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. Calculate the stem effect by dividing the difference of indicated value by the value obtained wdthout the shield.


Login to enter a peer comment or grade. The cahbration constant of a meter to be calibrated shall be obtained by the following formula. Radiation 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: Round off to one decimal tenth place Explanation: Moreover, for the radiation quality of X-rays, it is allowed to use the radiation quality notation specified by ISO In addition, jia dose equivalent rate is indicated by H icm.

I looked for it, and found many references to the standard, but was unable to find the standard his. Japanese term or phrase: Peer comments on this answer and responses from the answerer. JIS Z English: You can request verification for native languages by completing a simple application that takes only a couple of minutes.


When energy is 3 MeV or over, deviation from electronic equilibrium makes it impossible to accurately determine an exposure. The revision introduces an air kerma standard and concerns the fundamental matters of the system of calibration.

The calibration for confirmation does not specify a new calibration constant to the said meter. You will also have access to many other tools and opportunities designed for those who have language-related jobs or are passionate about them.
