This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 4835-2008 "Radiation protection instrumentation β, X and γ radiation surrounding and/or directional dose equivalent (rate) meters and / Or monitor ", compared with the GB/T 4835-2008, in addition to editorial changes outside the main technical changes are as follows. --- Standard name changed to "Radiation protection instrumentation β, X and γ radiation surrounding and/or directional dose equivalent (rate) meters and/or monitors Part 1. Portable workplace and environmental meters and monitors "; --- Modify the scope, clear in this section applies only to monitors and portable measuring instrument for use in the workplace and the environment; --- "2 Normative references" added some national and international standards referenced in the body of the standard; --- Modifications and additional terms and definitions; --- Added "Unit 4 and bulleted lists"; --- "Minimum measuring range" by deleting the contents of the relevant emergency (see the 2008 edition of 4.1.6); --- Increase the contents of the software; --- Added Appendix B (informative) and Annex C (informative). This section uses the translation method is equivalent to using IEC 60846-1. "Radiation protection instrumentation β, X and γ radiation around 2009 and/or directional dose Equivalent (rate) meters and/or monitors - Part 1. Portable workplace and environmental meters and monitors.

This part is proposed by the China National Nuclear Corporation. This part of the National Nuclear Instrument Standardization Technical Committee (SAC/TC30) centralized. This section is drafted. Xi'an Nuclear Instrument Factory, Institute of Nuclear Industry Standardization. The main drafters of this section. Sun Liping, Liangping, XU Xiao Wei. This Part replaces GB/T 4835-2008, GB/T 4835 was first released in December 1984, June 2008, the first amendment. Radiation protection instrumentation β, X and γ radiation surrounding and/or Directional dose equivalent (rate) meters and/or monitors Part 1. Portable workplace and environmental Measuring meters and monitors

1 Scope

GB/T 4835 This section applies to externally measure β, X and γ radiation of ambient dose equivalent (rate) and/or directional dose equivalent The amount (rate) of dose equivalent (rate) meters and/or monitors (by number ICRU47 recommendations of the report). Note 1. If you mentioned the ambient dose equivalent and directional dose equivalent, can be abbreviated as dose equivalent. This section only applies to portable measuring instrument and monitors for use in the workplace and in the environment. This section applies to externally measure β Dose and/or X and γ radiation dose equivalent rate or equivalent instruments, the dose range of 0.01μSv ~ 10Sv, dose rate range Is 0.01μSv · h-1 ~ 10Sv · h-1, the energy range are given in Table 1. All the energy value is the average amount of energy major dose. Table 1 portion of the measurement range and energy involved Measuring the amount of radiation energy range of photon energy range β radiation H * (10) 12keV ~ 10MeV - H '(0.07) 8keV ~ 250keV 0.07MeVa ~ 1.2MeV Almost equal to 225keV ~ 3.54MeV range Emax For a β radiation to penetrate 0.07mm (almost equal to ICRU tissue 0.07mm) deep layer of dead skin, the energy requirements of 0.07MeV. Note 2. The dose rate meter or monitor can be connected to the auxiliary probe for monitoring pollution, the relevant standard is applicable pollution monitoring probe GB/T 5202-2008. If national regulations require the use of different measurement quantities (for example. air kerma or exposure), after adjustment can also be used in this section. In this section, at the same time involving dose equivalent and dose equivalent rate measurements using the "dose equivalent (rate)." Note 3. This section does not apply to medical radiation equipment, radiation in medical radiation exposure can be very uneven, but accurately known. Note 4. This section does not apply for the evaluation of individual radiation doses received by the staff and worn equipment. The purpose of this section is to provide means for determining ambient dose equivalent (rate) and directional dose equivalent (rate) dose equivalent (rate) Instrument to Summation performance characteristics. This section provides. a) dose equivalent (rate) meter general characteristics, functions and performance characteristics; b) Test methods meet the requirements of this section.
