Peer comments on this answer and responses from the answerer agree. The value shall be obtained by the following formula. Printed in Japan. The radiation source and irradiation conditions are compared before change and after change.

Subtract its minimum from its maximum and divide the difference by its minimum. When obtaining the ratio of the indicated value at the time of calibration to iis initial indicated value, use half-life compensation of a radiation source.

In this case, a personal dosemeter shall be placed at the central part of the phantom and as close as possible to the phantom. JIS Z Term search All of ProZ. If there is no corresponding energy, it shall be found by interpolation. You have native languages that can be verified You can request verification for native languages by completing a simple application that takes only a couple of minutes.

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. Remarks 1 A user may specify the frequency of calibration for confirmation individually according to the performance of a meter, an intended use, operating conditions, etc.

The uncertainty in calibration shall be found the square root of the sum of the square of uncertainty of the field where a standard was set uncertainty of the calibration including the performance of a reference meter, or uncertainty of calibration of a reference 84011 -ray source and the sum of the square of uncertainty of a meter to be calibrated including uncertainty of calibration6 Uncertainty of calibration 6.

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.


Then, an ICRU-sphere dose-equivalent practical meter shall be calibrated by a substitution method. Remarks 1 Because the calibration distance is 2 m or over, the calibration distance may be measured on the jia of the phantom.

When the said energies are not a single energy, it is the effective energy. The calibration constant of a meter to be calibrated shall be obtained by the following formula. Post Your ideas for ProZ. Irradiation shall be performed using the practical y -ray source and irradiation conditions which were specified beforehand.

By using this, value determination of practical irradiation equipment shall be performed by an ICRU-sphere dose equivalent rate. The substance used as a filter shall be of four kinds- aluminum, copper, tin, and lead. Calculate the reproducibility of response from the calibration constant.

Late responding, but I agree on this. Moreover, the practical exposure rate standard is multiplied by the air absorbed dose conversion g factor in order to jjs vip the filed of the practical air absorbed dose rate standard. 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: Reviewing applications can be fun and only takes a few minutes.

Calculate the directional characteristic from the indicated value. The calibration for confirmation does not specify a new calibration constant to the said meter. 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 kis source is a y -ray source where a reference meter determines the value ji the exposure rate, the rate of an air kerma, or the dose equivalent rate of a radiation source.

It is referred to as “calibration tables”. The other is that the beam monitor which monitors the output change of irradiation equipment is concurrently used.

The revision responds to enforcement jix the new radiation hazard prevention related statute which incorporates the new Measurement Law effective as of April, and ICRP recommendation. When y -ray irradiation equipment with the similar value setting is used independently, it shall be included in this category. Participation is free and the site has a strict confidentiality policy. Next, suppose that the value would be obtained on the phantom. 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, utility model right or application for registration of utility model after opening to the public which have technical properties.


Totalizing type One point within jiz entire measuring range. Peer comments on this answer and responses from the answerer. In that case, the indicated value at the time of calibration for confirmation shall be obtained by performing the same number of measurements.

Calibration of area and personal dose meters and ji measurement of their response as jus 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. If the indication of the year of publication is given to these re erred standards, only the jid of the indicated year constitutes the provision of this Standard but the revision and supplement made thereafter do not apply.

Tn addition, the error of the dose-equivalent conversion factor for finding a dose-equivalent rate standard shall not be considered. Grading comment Thanks everybody 4 KudoZ points mis awarded for this answer. It can be performed only when the dosemeter of the same type is calibrated.

I looked for it, and found many references to the standard, but was unable to find the standard itself. 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. Calculate the linearity of scale from the calibration constant. You can request verification for native languages by completing a simple application that takes only 8041 couple of minutes.

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 x conditions of irradiation hereafter referred to as “initial indicated value”.
