Round to one decimal place. Reviewing applications can be fun and only takes a few minutes. JIS Z 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. General principles, Annex B Guide to the rounding of numbers http: Calculate the reproducibility of response from the calibration constant.
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.
Remarks 1 Because the calibration distance is 2 m or over, the calibration distance may be measured on the surface of the phantom. Round off to one decimal tenth place Explanation: 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.
Login or register free and only takes a few minutes to participate in this question. Calculate the linearity of scale from the calibration constant.
However, calibration for confirmation may be perfbrmed continually in the following case. 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 -ray source is a y -ray source where a reference meter determines the value of the exposure rate, the rate of an air kerma, or the dose equivalent rate of a radiation source.
By using this, value determination of practical irradiation equipment shall be performed by an ICRU-sphere dose equivalent rate. Finally, it can be proven that the continuity from the initial indicated value is maintained.
As necessary, the record at the time of calibration original calibration record shall be attached. Calculate the dose-rate characteristic by dividing the difference of calibration constant by its minimum. In that case, the indicated value at the time of calibration for confirmation shall be obtained by performing the same number of measurements.
JIS Z English: 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. Full text of ” JIS Z Login to enter a peer comment or grade.
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.
When y -ray irradiation equipment with the similar value setting is used independently, it shall be included in this category. 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.
Irradiation shall be performed using the practical y -ray source and irradiation conditions which were specified beforehand. The KudoZ network provides a framework for translators and others to assist each other with translations or explanations of terms and short phrases. 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.
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.
The revision responds to enforcement of the new radiation hazard prevention related statute which incorporates the new Measurement Law effective as of April, and Jus recommendation.
Peer comments on this answer and responses from the answerer.
Figure 3 In the case of a non-collimate y -ray mis X-ray irradiation equipment shall be as specified in figure 4. Automatic update in When the said energies are not a single energy, it is the effective energy. Printed in Japan. The filter for half-value-layer measurement shall be of three kinds- aluminum, copper, and tin. 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 jjis irradiation hereafter referred to as “initial indicated value”.
Late responding, but I agree on this. 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. Grading comment Thanks everybody 4 KudoZ points were awarded for this answer.
In addition, this dose equivalent rate is indicated by H icm.
JIS Z 8401:1999 English Edition
Synthesis of uncertainty shall be the square root of the sum of square of the uncertainty related to each event. In this Standard, an air absorbed dose practical meter is included in an air kerma practical 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. Grading comment Thanks everybody. When energy is 3 MeV or over, deviation from electronic equilibrium makes it impossible to accurately determine an exposure.
