STATE OF NEW HAMPSHIRE MERRIMACK, SS. May 19, 1986 The above-subscribed William T. Wallace, Jr., appeared before mc and made oath that he had read the foregoing affidavit and that the statements set forth therein are true to the best of his knowledge.

Before me, AM - 1/2 Notary Public My Commission Expires: [-/6-N l

l l

- Defense upon declaration of a SITE AREA EMERGENCY. State workers will receive their dosimeters from a NHCDA representative located at each of the following facilities:

IF0/ EOF, State Transportation Staging Area, State Police Troop A Headquarters, and Department of Transportation, Division 5 Headquarters.

Once releases of radioactive materials have occurred, each worker will De required to take readings from the self-reading dosimeter and report the readings to their respective EOC and IF0/ EOF at pre-determined levels. After the event has been terminated, the dosimeters will be returned to local Civil Defense personnel in the respective EOCs. If emergency workers have been ordered to evacuate the area, the dosimeters will be turned in to the DPHS representative in the IF0/ EOF. If the emergency extends for several days, the TLDs will be replaced by the vendor and actual dose recorded. After the emergency is terminated, all TLDs will be collected by DPHS to determine actual exposures for permanent records.

OPHS is responsible for emergency worker exposure records.

Log Sheets will be maintained in each local EOC and in the IF 0 / EO F . A sample Personnel Exposure Record is shown in Figure 2.7-1. After the emergency has been terminated, all Personnel Exposure Records will be collected by DPHS and kept as a permanent record.

2.7.3 Thyroid and Respiratory Protection Both the self-reading dosimeters and TLDs record external whole body gamma exposure. They do not have the capacity to separately monitor Iodine-131. KI will be stored in the local EOCs and at the IF0/EOFs. For Seabrook Station KI will also be stored with dosimetry at staging areas, Troop A Headquarters and Division #5 Headquarters.

!.- Emergency Workers I

I Based on actual and anticipated releases, DPHS will determine when KI shall be distributed to State and local emergency workers. If the power plant has released I-131, and if projected doses are expected to exceed the upper range of the general population PAG for thyroid exposure (25 rem), the use of KI for emergency workers will be considered. (Ref.

! State DPHS KI Policy Memo cited in Section 4.1).

Protecting an individual from I-131 exposure by means

other than KI also protects the lungs against all other

! inhalable radionuclides. This is because the protective

! actions that limit inhalation of I-131 occur well before lung exposure from other radionuclides become a concern. Once an ,

emergency worker has been protected from 1-131 by KI, however, lung exposures from other inhalable radionuclides become important. If releases of these other radionuclides are projected to occur in amounts that require protection, local emergency workers will be removed from the area. OPHS will decide which State emergency workers will be allowed to return i

i to contaminated areas and may require them to wear respiratory protection devices or to limit the time of their exposure.

Institutionalized Individuals KI will be made available, in the event of a radiological emergency, to institutionalized individuals. Institutionalized individuals are individuals who are patients in hospitals, residents in a nursing home licensed as such by the Division of Public Health Services, individuals who are confined in a house of correction, or who are staff employed by the hospital, nursing home or house of correction and whose presence in the facility is unavoidable during a radiological emergency.

The KI will be made available to be ingested by all staff f

i and by confined individuals only after instruction to do so by DPHS. Ingestion by hospital patients and residents of nursing l

1236/7812A/0086C 2.7-5 Rev. 1 6/86 l l -

l j

homes will also be only after instruction to do so by DPHS, and only if the individual's physician has determined that the use of KI is appropriate for the individual. Such determination may be made in advance and noted in the individual's medical records.

2.7.4 Radiological Exposure Control Decision Criteria DPHS is responsible for all decisions relating to radiological exposure of State and local emergency workers.

DPHS personnel located in the IF0/ EOF will be kept informed of local emergency worker exposures via the local EOC and will be directly responsible for State workers. At pre-determined dose levels, DPHS will either order emergency workers to leave the area or authorize increased exposures. In no case will an emergency worker be allowed to exceed the EPA PAGs established for emergency workers (See Table 2.6-1).

The decision process that DPHS will follow is shown in Figure 2.7-2. When SITE AREA EMERGENCY activity begins, all emergency workers will be equipped with three dosimeters end, if releases are expected, they will be ordered to read them every 15 minutes (Block A). The dosimeter readings will be reported to their local EOC and IF0/ EOF as predetermined exposures are reached.

There are two different exposure pathways which must be considered in radiological exposure control each of which relates to different releases from the plant. Therefore, the next question asks what is being released from the power plant (Block B). If only noble gases have been or are being released, only whole body exposure is important and the dosimeters provide sufficient information to protect emergency workers. The first reporting level (Block C) is a CDV-138 reading of 175 mR, which is well below the PAG for the general 1236/7812A/0086C 2.7-6 Rev. 1 6/86

APPENDIX K Potassium Iodide (KI) Administration

1. PURPOSE:

This procedure provides guidance and instruction for the authorization, distribution and administration of radioprotective drugs (Potassium Iodide

- KI) to local and state emergency workers.

2. RESPONSIBILITIES:

A. The DPHS Director is responsible for authorizing emergency workers to take KI.

8. The NHCDA Director is responsible for informing local EOC's of the decision to take KI.

C. The local EOC RADEF officers are responsible for informing local EOC emergency workers of the decision to take II.

D. The IF0/ EOF Coordinator is responsible for informing state emergency workers of the decision to take KI.

E. The IF0/ EOF RHTA is responsible for the administrative coordination of the issuence of KI.

F. The state and local emergency workers are responsible for maintaining their KI record sheets.

3. ACTIONS:

The following actions are to be taken by the local EOC Radef Officers and the IF0/ EOF Field Monitoring Team / Decontamination Coordinator:

Predistribution A. Upon arrival at the EOC, remove the KI tablet bottles from their storage location and verify that the bottles have not exceeded their shelf life. If bottles are out-of-date, contac the DHPS Director for replacement supplies.

B. Advise each emergency worker the the use of KI is voluntary. Review the KI Consent Form (Attachment 1) and ensure the individual signs the form.

C. Issue ONE KI tablet to each emergency worker and tell them NOT to take the tablet unless directed by their supervisor.

DO NOT DISTRIBUTE ANY TABLETS THAT ARE BEYCND THEIR INDICATED EXPIRATION DATE.

D. Make an entry on the individual's Potassium Iodide Record Sheet (Attachment 2) indicating the distribucion of the tablet, los the results on both the individual's and record copies. IF they are told to take the first tablet, instruct the individual to report the following day (with his copy of the record sheet) to receive the next tablet.

E. Ensure copies of all records (Attachments 1 and 2) ante forwarded to the IF0/ EOF RHTA.

XI Issuance Criteria A. IF0/ EOF RHTA

1) Complete the KI Vorksheet (Attachment 3).

2) Upon the determination of the need for emergency workers to take XI, recommend that the IF0/ EOF Coordinator receive authorization from the DPHS Director. . .

NOTE: The effectiveness of KI to block the uptake of radiciodines diminishes with time after initial e{posure. Therefore, the decision of when to issue KI will consider the time available for maximum effectiveness according to the following guidelines:

a) Vithin one hour after exposure .............. 90% effective.

b) 3-a hours after exposure .................... 50% effective.

c) 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after exposure ................ .....very small effect.

KI Use Criteria A. Emergency Workers:

1) Upon proper authorization and notification from the local EOC Radef Officer as IF0/ EOF Coordinator, take their KI tables.

2) Complete Attachment 2. KI Record Sheet.

3) Report to your EOC as IF0/ EOF the nort day to receive the second tablet. Bring your copy of Attachment 2.

I APPENDIX K Attachment 1 POTASSIUM IODIDE ACKNOWLEDGEMEC FORM I will not take my first XI tablet until I receive instructions to do so. If instructed to do so, I, , understand that in order to obtain maximum protection for the thyroid I will receive 130 milligrams per day for the next 10 days of the thyroid blocking agent potassium iodide. I have been informed that this drug will block the absorption of radio-iodine by my thyroid and thereby reduce the exposure to radiation of the thyroid; that potassium iodide does not reduce the uptake of other radioactive materials by the body; nor, does it provide protection against exposure from external radiation. I have been told that if I en allergic to iodide that I should not take potassium iodide.

SIGNATURE DATE When completed, copies of this form should be forwarded to the IF0/ EOF RHTA.
