It can be performed only when the dosemeter of the same type is calibrated. Figure 3 In the case of a non-collimate y -ray b X-ray irradiation equipment shall be as specified in figure 4.

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

Synthesis jix uncertainty shall be the square root of the sum of square of the uncertainty related to each event. Round off to one decimal tenth place. Late responding, but I agree on this. Express the quotient in percentage. View Ideas submitted by the community. In this Standard, an air absorbed dose practical meter jia included in an air kerma practical meter. Peer comments on this answer and responses from the answerer agree.

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. Practical y -ray irradiation equipment is assigned a value by the ICRU-sphere dose equivalent rateand it can set a practical ICRU’sphere dose-equivalent rate standard.

Close and don’t show again Close. Consequently JIS Z Subtract its minimum from its maximum and divide the difference by its minimum. Use a practical meter having a definite calibration constant, and compare the value indicated after certain period of use since it was put iis use, with the value indicated at the start by the same conditions of irradiation hereafter referred to as “initial indicated value”.

You can request verification for native languages by completing a simple application that takes only a couple of minutes. Participation is free and the site has a strict confidentiality policy. Calculate the stem effect by dividing the difference of indicated value by the value obtained wdthout the shield.

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. 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.

Reviewing applications can be fun and only takes a few minutes.

The coefficient of variation shall be 0. In this case, a personal dosemeter shall be placed at the central part of the phantom and as close as possible to the phantom.

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. Similarly, an air kerraa and air absorbed dose per unit time are called “the rate of an air kerma”, and “rate of an air absorbed dose”, respectively. Automatic update in As necessary, the record at the time of calibration original calibration record shall be attached.

Grading comment Thanks everybody 4 KudoZ points were awarded for this answer. 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.

I think cinefill is right.

Calibration of area 88401 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.
