NCR - occupational radiation exposure limits

Compliance with occupational radiation exposure limits

Allowable occupational radiation exposure limits set by the government

In addition to ALARA protocol, which we discussed here, the United Stated Department of Energy (DOE) recommends the review of 9 applicable requirements, guidance, and standards to ensure minimal exposure to radiation.
These are:
  • 10 C.F.R.835, Occupational Radiation Protection, establishes radiation protection standards, limits, and program requirements for protecting individuals from ionizing radiation resulting from the conduct of DOE activities. Subpart I, “Reports to Individuals,”requires reporting of data to individuals monitored in accordance with 835.402.
  • 10 C.F.R.835.402 (b) and(d),“Individual Monitoring,”requires implementing external and internal dose monitoring programs that are accredited, or excepted from accreditation, in accordance with the DOELAP.
  • DOE Order 231.1-1B, Environment, Safety and Health Reporting, requires reporting of the individual occupational radiation exposure data to the REMS repository.
  • REMS Reporting Guide, provides details about the data format and schedule for reporting.
  • DOE Order 210.2 A, DOE, Corporate Operating Experience Program, requires collection, analysis, and dissemination of performance indicators, such as occupational radiation exposure information.
  • DOE System of Records DOE-35, Personnel Radiation Exposure Records, establishes requirements for routine use of the data.
  • DOE-STD-1111-98, DOE Laboratory Accreditation Program Administration.
  • DOE-STD-1095-2011, DOE Laboratory Accreditation for External Dosimetry.
  • DOE-STD-1112-98, DOE Laboratory Accreditation Program for Radiobioassay.
ALARA - Allowable Radiation Limits when using x-ray for NDT inspectionIn addition, the U.S. Nuclear Regulatory Commission, has an issued government regulations, 10 CFR 20; Standards for Protection Against Radiation, which states:
… allowable occupational radiation exposure limits are 5,000 MR/year for whole body (head, trunk, arms above the elbow, legs above the knee) and 50,000 MR/year for extremities (hands, elbows, arms below the elbows, foot, knee or leg below the knee.)

Is CXR Company and its x-ray equipment within compliance?

CXR’s x-ray inspection equipment emits no more that .5 MR/hour at five centimeters, or one inch, from any surface of the machine.

If an employee should stand 1 inch away from the unit for 8 hours a day for a working year of 200 days, s/he would receive, at most, 800 MR/year which is less than 20% of the allowed maximum.

Simple out, YES!

CXR’s x-ray inspection systems are safe and in compliance with all government regulations and suggested protocol.
