CDP Radiation Safety Program Annex B Safety Standards, Dosimetry, and Recordkeeping Rev. 0 (Mar 10)

Annex B Safety Standards, Dosimetry, and Recordkeeping

It is the responsibility of the licensee and all users of radiation sources to conduct operations to ensure that radiation exposures received by workers and members of the general public are below those limits established by Federal and State regulations. Furthermore, doses shall be maintained at levels that are As Low As Reasonably Achievable (ALARA).

2. IONIZING RADIATION.

a. The Code of Federal Regulations (CFR) Title 10, Part 20, prescribes the maximum annual exposures to workers and members of the general public. While it is understood that 10 CFR applies only to the NRC Licensed materials, the CDP accepts those limits for all sources of ionizing radiation.

b. The following table identifies the standards as specified by 10 CFR

Part 20:

Category Maximum 1,2,3 Member of the General Public 100 mrem (TEDE) in a calendar year4 Fetus/embryo of occupationally exposed declared pregnant worker

500 mrem (DDE of mother + ED due to radionuclides in fetus/embryo) for entire pregnancy

Occupationally Exposed Adult 5 rem TEDE in a calendar year Lens of the Eye 15 rem EDE in a calendar year Individual Organ 50 rem DDE+CDE in a calendar year Skin or Extremity 50 rem SDE in a calendar year Occupationally Exposed Minor 10% of applicable limit for adult

1. Maximum doses will be the limit listed in this table or the current version of 10 CFR Part 20, which ever is the most restrictive.

2. Abbreviations: TEDE = Total Effective Dose Equivalent; DDE = Deep

Dose Equivalent; ED = Effective Dose; EDE = Effective Dose Equivalent;

CDE = Committed Dose Equivalent; SDE = Shallow Dose Equivalent

3. OSHA standard for occupational exposure of adults and for the lens of the eye is 1¼ rem in a calendar quarter. OSHA standard for skin of whole body is 7½ rem in a calendar quarter. OSHA standard for hands and forearms; feet and ankles is 18¾ rem in a calendar quarter.

4. The dose in any unrestricted area from external sources of ionizing radiation will not exceed 2 mrem in any one hour.

c. All CDP employees conducting operations involving ionizing radiation sources must comply with the above exposure criteria.

d. Dosimetry. Occupationally exposed individuals requiring monitoring will only use dosimeters supplied by the CDP RSO. The CDP Dosimetry Program will be managed by the CDP RSO.

(1) Dosimetry will be issued based on the following criteria:

(a) Personnel likely to receive 10% of any limits established above.

(b) Personnel entering restricted areas where the external radiation requires the posting of a "Radiation Area, High Radiation Area, or Very High Radiation Area" sign.

(c) Personnel not permanently assigned to the CDP meeting the requirements above may be issued a dosimeter as a "Visitor/Student".

(2) Storage of dosimeters while not being worn will only be allowed in locations authorized by the CDP RSO.

(3) Individuals assigned dosimeters will contact the CDP RSO immediately if any of the following situations occur:

(a) Dosimeter is lost or damaged during wear period.

(b) Dosimeter is inadvertently exposed (i.e. dosimeter falls off during set-up and not noticed until after exposure.)

(c) Dosimeter is worn by an individual other than the individual it is assigned.

3. RADIOACTIVE CONTAMINATION.

a. Operations with radioactive materials will be conducted to ensure that radioactive contamination is avoided.

b. Contamination in "restricted areas" will be maintained below the applicable levels in the table below:

1. Where surface contamination by both alpha and beta-gamma nuclide exists, the limits established for alpha and beta-gamma emitting nuclides should apply independently.

2. As used in this table, dpm (disintegrations per minute) means the rate of emission by radioactive material as determined by correcting the counts per minute observed by an appropriate detector for background, efficiency, and geometric factors associated with the instrumentation.

3. Measurements of average contamination should not be averaged over more than 1 square meter. For objects of less surface area, the average should be derived for each object.

4. The maximum contamination level applies to an area of not more than 100 cm2.

5. The amount of removable radioactive material per 100 cm2 of surface area should be determined by wiping that area with filter or soft absorbent paper, applying moderate pressure, and assessing the amount of radioactive material on the wipe with an appropriate instrument of known efficiency. When removable contamination on objects of less surface area is determined, the pertinent levels should be reduced proportionally and the entire surface should be wiped.

c. Areas of contamination above the limits stated above will be decontaminated to levels below those listed.

d. Equipment stored and/or used in restricted areas identified for release to unrestricted areas will be surveyed to ensure that contamination levels are as far below the limits as practicable.
