You can request verification for native languages by completing a simple application that takes only a couple of minutes. Moreover, 70 ,u m dose equivalent in connection js an individual is the dose equivalent in the depth js 70 u m.

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. 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.

The contents shall be as follows- In addition, method to round numbers shall be as specified in JIS Z 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. When y -ray irradiation equipment with the similar value setting is used independently, it shall be included in this category.

First, a meter to be calibrated is used. Next, suppose that the value would be obtained on the phantom. Finally, it can be proven that the continuity from the initial indicated value is maintained. Calculate the dose-rate characteristic by dividing the difference of calibration constant by its minimum. As for the quality of the material of the substance used for the filter, the purity shall be 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 y -ray source and the sum of the square of uncertainty of a meter to be calibrated including uncertainty of calibration6 Uncertainty of calibration 6.


General principles, Annex B Guide to the rounding of numbers http: Login to enter a peer comment or grade. It can be performed only when the dosemeter of the same type 88401 calibrated. One is that a meter to be calibrated and 88401 reference instrument specified in ISO “3 are simultaneously irradiated. I think cinefill is right. If there is no corresponding energy, it shall be found by interpolation.

By using this, value determination of practical irradiation equipment shall be performed by an ICRU-sphere dose equivalent rate. JIS Z English: Remarks 1 Because the calibration distance is 2 m or over, the calibration distance may be measured on the surface of the phantom.

Post Your ideas for ProZ. The radiation source and irradiation conditions are compared before change and after change. Grading comment Thanks everybody. 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.

The record shall be maintained to enable continual confirmation. The calibration constant of a meter to be calibrated shall be obtained by the following formula.

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 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. View forum View forum without registering on UserVoice.

Moreover, the same radiation source shall be used through the usable years of a meter. Then, an ICRU-sphere dose-equivalent practical meter shall be calibrated jos a substitution method. 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.


Term search All of ProZ. Late responding, but I agree on this. Round off to one decimal tenth place.

Consequently JIS Z But, it should have intense enough to fully verify the validity of the calibration constant of a meter to be calibrated. Table 3 4801 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: 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.

Patents, Trademarks, Copyright Law: 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. The calibration constant N of a dosenieter to be calibrated shall be obtained by the following formula.

JIS Z 8401:1999 English Edition

84401 Synthesis of uncertainty shall be the square root of the sum of square of the uncertainty related to each event. Vote Promote or demote ideas. View Ideas submitted by the community. The filter for half-value-layer measurement shall be of three kinds- aluminum, copper, and tin.

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 jls JIS Z and the following definitions apply.

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