Tab 9 EP-PS-1 10-9 PPL EMERGENCY PERSONNEL DOSE ASSESSMENT AND PROTECTIVE ACTION RECOMMENDATION (PAR) GUIDE CHECK D 1.0 Limits for EMERGENCY doses.
D 1.1 An EMERGENCY DOSE AUTHORIZATION (see EMERGENCY EXPOSURE EXTENSIONS) may be granted in order to protect facilities, and or equipment to substantially limit the escape of radioactive effluents or control fires. The maximum planned doses are:
1.1.1 Whole body (TEDE)1) dose shall not exceed 10 rem.
1.1.2 Dose to any organ (CDE)(2), including the skin and extremity (SDE)( 3 ), shall not exceed 100 rem.
1.1.3 Dose to the lens of the eye shall not exceed 30 rem (LDE)(4).
o 1.2 An EMERGENCY dose authorization may be granted for life-saving actions or protection of large populations. The maximum doses are:
1.2.1 Planned whole body (TEDE)( 1 ) doses shall not exceed 25.rem.
1.2.2 Planned dose to any organ (CDE)(2), including skin and extremity doses, shall not exceed 250 rem.
1.2.3 Dose to the lens of the eye shall not exceed 75 rem (LDE)(4).
1.3 RARE situations may occur in which a dose GREATER THAN those specified in SECTION 1.2 above for emergency dose would be unavoidable to carry out a lifesaving operation or to avoid extensive exposure of large populations. It is not possible to prejudge the risk that one should be allowed to take to save lives of others, therefore no upper limit has been established.
(1) The sum of the Effective Dose Equivalent resulting from the exposure to external sources and the Committed Effective Dose Equivalent incurred from all significant inhalation pathways during the early phase.
(2) The Committed Dose Equivalent to the thyroid from radioiodine.
(3) Shallow Dose Equivalent.
(4) Lens Dose Equivalent.

Tab 9 EP-PS-1 10-9 PPL EMERGENCY PERSONNEL DOSE ASSESSMENT AND PROTECTIVE ACTION RECOMMENDATION (PAR) GUIDE CHECK D 2.0 For any EMERGENCY EXPOSURE OR ACCIDENTAL OVEREXPOSURE, the assessment actions in step 2 of the EMERGENCY EXPOSURE EXTENSIONS must be performed.
3.0 PROTECTIVE ACTIONS D 3.1 Potassium Iodide 3.1.1 For thyroid doses that are strongly expected to exceed 10 rem (CDE) (2), ingestion of a KI dose of 130 mg (100mg - iodine) should be recommended, except as noted in paragraph 3.1.2, to personnel whose emergency assignment or qualifications do not allow other protective measures to be taken (e.g. respiratory protection, evacuation, relocation, etc.) to maintain the dose to the thyroid at less than 10 rem.
NOTE: HHS/FDA guidance is that adults over 40 years of age need take KI only in the case of a projected large internal radiation dose to the thyroid (-> 500 rem) to prevent hypothyroidism; the guidance is 10 rem for adults over age 18 to age 40.
3.1.2 KI should not be administered to any emergency worker who:
- a. does not concur with its use, or
- c. has been directed by their Physician or Pharmacist to avoid ingestion of iodine and/or foods containing iodine such as shellfish.
(2) The Committed Dose Equivalent to the thyroid from radioiodine.
EP-AD-000-125, Revision 9, Page 3 of 13
Tab 9 EP-PS-1 10-9 PPL EMERGENCY PERSONNEL DOSE ASSESSMENT AND PROTECTIVE ACTION RECOMMENDATION (PAR) GUIDE CHECK 0 3.1.3 Onsite issuance of KI for iodine prophylaxis requires the approval of the EMERGENCY DIRECTOR. Issuance to EOF and FIELD EMERGENCY MONITORING/SAMPLING TEAM personnel requires the approval of the RECOVERY MANAGER when the EOF has relieved the TSC of emergency management activities.
The EMERGENCY DIRECTOR will approve issuance prior to that time. These approvals must be documented on the POTASSIUM IODIDE (KI) TRACKING FORM.
3.1.4 Unless the EMERGENCY DIRECTOR or RECOVERY MANAGER instructs personnel to do otherwise, the KI tablets should generally be taken as soon as possible after thyroid dose exceeding 10 rem CDE (2) is projected.
NOTE: Stable iodine (KI) is most effective when administered immediately prior to exposure to radioiodine. Significant blockage of the thyroid dose can be provided by administration within a few hours after uptake of radioiodine.
3.15 In the event a significant exposure to the thyroid is projected to continue over a period of several days the CONSULTING RADIOLOGICAL PHYSICIAN should be requested to provide a recommended KI dosage for subsequent KI usage. (See Emergency Telephone Directory for telephone number.)
3.16 Until input/advice from the CONSULTING RADIOLOGICAL PHYSICIAN is available, a quarter of a tablet should be taken on days of exposure that follow the day on which the initial full tablet dose (130 mg) was taken.
3.17 If a worker expresses concern with the use of KI and/or is unsure if it will interact with his/her current medication,
- a. the CONSULTING RADIOLOGICAL PHYSICIAN should be requested to provide inpuVadvice to the individual concerning the administration and cessation of KI use prior to its ingestion by the individual. (See Emergency Telephone Directory for telephone number.)
(2) The Committed Dose Equivalent to the thyroid from radioiodine.
EP-AD-000-125, Revision 9, Page 4 of 13
Tab 9 EP-PS-1 10-9 PPL EMERGENCY PERSONNEL DOSE ASSESSMENT AND PROTECTIVE ACTION RECOMMENDATION (PAR) GUIDE CHECK 0
- b. control and track workers' dose, to limit their projected thyroid dose to 40 rem total organ dose. As warranted, ensure adjusted RWP controls and dose extensions are in place.
3.1.8 Should the projected dose to the thyroid not exceed 10 rem CDE (2)but the worker expresses the strong desire to use KI, the worker may do so at his/her own risk. In such case, the RPC or DASU as appropriate will inform the worker of the potential risks and benefits as described below and will recommend the person contact the CONSULTING RADIOLOGICAL PHYSICIAN for further guidance.
NOTE: Radiation exposure to the thyroid glands of adults does not appear to lead to cancer but has been shown to cause other deterministic effects (such as hypothyroidism resulting from thyroid ablation) from very high radiation doses to the thyroid.-
For persons over 40 years of age, HHS/FDA recommends KI only for projected doses to the thyroid of above 500 rem, to prevent hypothyroidism.
The National Council on Radiation Protection and Measurement (NCRP Report No. 55) concludes that the risk of adverse effects from use of KI is on the order of 5 in 10 million.
In some cases, hyperthyroidism (excessive functional activity of the thyroid gland) is possible.
Those most at risk are patients with thyroid pathologies. This is most common in patients with goiter. This complication can be serious when the person also has heart disease. The risk of adverse effects is higher in adults of age 45 years and older, due to the frequency of diagnosed and sub-clinical thyroid disease and the use of certain prescription pharmaceuticals that would lead to a drug interaction.
(2) The Committed Dose Equivalent to the thyroid from radioiodine.
EP-AD-000-125, Revision 9, Page 5 of 13
I Tab 9 EP-PS-1 10-9 PPL EMERGENCY PERSONNEL DOSE ASSESSMENT AND PROTECTIVE ACTION RECOMMENDATION (PAR) GUIDE CHECK 0 HHS/FDA observes that short-term administration of KI at thyroid blocking doses is safe. The risks of stable iodine administration include sialadenitis (an inflammation of the salivary gland), gastrointestinal disturbances, allergic reactions, and minor rashes.
Other risks may apply if repeated doses of KI are ingested.
3.1.9 If the individual states the intent to take KI absent a projected dose of 10 rem (CDE)(2) or more, the RPC or DASU will document in his/her logbook that individual's intent, that information on risks and benefits was described to the individual, and the statement that the individual was notified that ingestion was at the individual's own risk.
3.1.10 For an injured and/or contaminated worker sent to a hospital for treatment, the patient will be under the care of the attending physician. As such, plant procedures no longer apply and KI issuance will be at the discretion of the attending physician. The physician can rely on a senior Health Physics Technician Level II or Health Physics Management to provide the in-plant radiological data on which to base their decision.
o 3.2 Protective measures should be implemented for EOF personnel at the direction of the DOSE ASSESSMENT SUPERVISOR, within the bounds of RWPs #8001 and #8002. Consultation with and approval by the RPC is needed for RWP revisions.
o 3.3 Exposures to members of local offsite support groups, (ambulance workers, fire fighters) shall not exceed 500 mrem (TEDE)(') for the performance of support duties on the site of the Susquehanna SES.
(2) The Committed Dose Equivalent to the thyroid from radioiodine.
The sum of the Effective Dose Equivalent resulting from the exposure to external sources and the Committed Effective Dose Equivalent incurred from all significant inhalation pathways during the early phase.

- 1. Fill out the attached EMERGENCY EXPOSURE EXTENSION REQUEST Form.
- 2. Review the following factors:
O Rescue personnel should be volunteers or professional rescuers.
O Other considerations being equal (e.g., skill, potential need for person on another mission) personnel above the age of 45 are preferred.
Eo Rescue personnel should be familiar and briefed with the consequences of exposure.
O Women capable of reproduction should not take part in an effort requiring EMERGENCY exposure.
D Use of personnel with high lifetime cumulative exposure should be discouraged.
