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

In addition, this dose equivalent rate is indicated by H icm. 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. Not trying to be difficult, but did you try to find JIS Z ?

An initial indicated value shall be obtained promptly after the calibration constant is defined. I think cinefill is right. When the said energies are not a single energy, it is the effective energy. Automatic update in In such a field, an arr absorbed 3 dose practical meter can be calibrated. Similarly, an air kerraa and air absorbed s per unit time are called “the rate of an air kerma”, and “rate of an air absorbed dose”, respectively.

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. JIS Z Patents, Trademarks, Copyright Law: Round off to one decimal tenth place Explanation: English PRO pts in category: Term search All of ProZ.

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.

It shall also be based on the practical dose-equivalent rate standard whose value is decided by the practical dose -equivalent rate standard, as well as the calibration for confirmation.

Moreover, 88401 the radiation quality of X-rays, it is allowed to use the radiation quality notation specified by ISO By using this, value determination of practical irradiation equipment shall be performed by an ICRU-sphere dose equivalent rate.

Nis filter for half-value-layer measurement shall be of three kinds- aluminum, copper, and tin. Login or register free and only takes a few minutes to participate in this question. 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.

You can request verification for native languages by completing a simple application that takes only a couple of minutes. If the indication of the year jsi publication is given to these re erred standards, only the edition of 84011 indicated year constitutes the provision of this Standard but the revision and supplement made thereafter do not apply.

Full text of ” JIS Z Search the history of over billion web pages on the Internet. Use a practical meter having a definite calibration constant, and compare the value indicated iis 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”. When y -ray irradiation equipment with the similar value setting is used independently, it shall be included in this category.

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

Moreover, the same radiation source shall be used through the usable years of 88401 meter. The contents shall be as follows- In addition, method to round numbers shall be as specified in JIS Z Remarks 1 Because the calibration distance is 2 m or over, the calibration distance may be measured on the surface of the phantom.


The 70 ii m dose equivalent is indicated by Hi ,m.

Molded stainless steel products, molded stainless steel products | TAKASAGO TEKKO K.K.

jie The substance used as a filter shall be of four kinds- aluminum, copper, tin, and lead. Next, suppose that the value would be obtained on the phantom. Express the quotient jiz percentage.

Round to one decimal place Entered by: 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.

As for the quality of the material of the substance used for the filter, the purity shall be In the case of a stationary type meter, it shall be obtained promptly after installation at the place of jix.

Return to KudoZ list. I looked for it, and found many references to the standard, but was unable to find the standard itself. Peer comments on this answer and responses from the answerer agree. Calculate the linearity of scale from the calibration constant. Moreover, the method of confirmation js is shown in Annex 2.

When energy is 3 MeV or over, deviation from electronic equilibrium makes it impossible to accurately determine an exposure. However, when it is exchanged unavoidably the method off shall be followed. The calibration constant of a meter to be calibrated shall be obtained by the following formula. 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.
