DOSE LIMITS TO MEMBERS OF THE PUBLIC EXPOSED TO HOSPITAllZED PATIENTS Supplementary information: Enclosed for your information and comment is a draft rulemaking plan entitled " Revision of Dose Limit for Members of the Public Exposed to Hospitalized Patients (10 CFR Part 20)." The NRC received a Petition for Rulemaking (PRM 20-24) dated April 24,1996, from the University of Cincinnati. The petitioner requests that the NRC amend 10 CFR 20.1301, " Dose limits for individual members of the public," to authorize specified visitors" of hospitalized radiation therapy patients, as individual members of the public, to receive up to 500 mrem per year. The staff proposes to amend Section 20.1301 to allow authorized user physicians the discretion to permit consenting adult care givers to receive up to 500 mrem (5mSv) annually from exposure to radiation patients.

A brief discussion of Agreement State implementation issues relative to this amendment is found on pages 5 6 of the enclosed draft Rulemaking Plan. The rulemaking process provides the Agreement States an opportunity to comment on the draft Rulemaking Plan prior to final approval. Because the draft Rulemaking Plan is pre-decisional, we request that you limit distribution to your staff and not release the document publicly to the extent permitted by State law.

Please review the material and direct any comments you may have by June 13,1997 to:

Rulemaking Plan Response to Request for Rulemaking 10 CFR Parts 20,35 PRM 20-24 University of Cincinnati Regulatory issue The NRC received a Petition for Rulemaking (PRM 20-24) dated April 7,1996, from the University of Cincinnati. The petitioner requests that the NRC amend 10 CFR 20.1301," Dose limits for individual members of the public," to authorize *specified visitors" of hospitalized radiation therapy patients, as individual members of the public, tc receive up to 500 mrem (5 mSv) per year.

The amendment proposed by the petitioner would provide medicallicensees the discretion to permit those visitors determined by the physician to be necessary for the emotional or physical support of the patient (e.g., parents of very young radiation therapy patients, close family members of elderly patients, or other persons who could provide emotional support to the patient) to receive up to 0.5 rem (5 mSv). Furthermore, the petitioner proposes excluding pregnant women and individuals younger than 18 years of age from receiving a dose in excess of 0.1 rem (1 mSv). Finally, the petitioner suggests that compliance could be documented by issuing radiation dose monitoring devices (i.e., pocket dosimeter, film badge, TLD or electronic dosimeter) to each specified visitor.

On June 21,1996 (61 FR 31874), the NRC published a notice of receipt and a request for comment on the petition. Comments were received from four members of the general public.

All commenters agreed with the petition. One of the commenters suggested that the previous 0.5 rem (5 mSv) dose limit for the general public be reinstated for family members and, under unusual circumstances, also permit the attending physician to authorize even higher dose limits provided the latter does not exceed the occupational dose limit.

Existing Regulatory Framework It is acknowledged in Part 20 that there may be instances that warrant individual members of the public receiving a dose in excess of the 0.1 rem (1 mSv) limit. Specifically, under the provisions of @ 20.1301(c), licensees may request NRC authorization to operate up to an annual dose limit for individual members of the public of 0.5 rem (5 mSv). However, the Statements of Consideration for the 1991 revision of Part 20 clearly indicate that this provision was intended for temporary situations to alleviate an immediate need to redesign a facility (56 FR 23375).

'The 0.5 rem limit is intended to be applied primarily to temporary situations where operation of a facility, or the person's exposure to radiation and radioactive emissions, is i not expected to result in doses above 0.1 rem over long periods of time. For design of

$ new installations, the 0.1 rem limit should be used. However, existing facilities may apply

[ for NRC approval to use the 0.5 rem limit while more complete evaluation of the need for

[ any additiona! modifications is performed. Such facilities may include, for example, F '

~

a

3P 2

hospitals with existing teletherapy machines that were designed, constructed, and installed to comply with a 0.5 rem annual dose limit."

The NRC has received few requests to allow care givers' of radiation patients to exceed the 0.1 il rem (1 mSV) public dose limit. In light of the above, it is possible that licensees generally are l reluctant to request such authorization, either because they do not believe the provision would apply or because of the administrative or financial burden associated with such a request. e@

l (Section 20.1301(c) requires fairly, complete documentation of the circumstances of the request and the licensee's proposal to make changes so the dose limit will not be exceeded in the @[

l future). Therefore, denying this petition would restrict and possibly prohibit close contact Q l between care givers and patients at a time when the physical and emotional support provided by 3 f;l such individuals is of great perceived benefit to both the patient and the care giver.

How the Regulatory Problem Will be Addressed By Rulemaking w

An appropriate change in the Commission's regulations would permit authorized user physicians /

the discretion to permit care givers to receive doses in excess of the 0.1 rem (1 mSv) public [

dose limit in the course of providing physical and emotional support to radiation diagnostic and 7;,

therapy patients, g

)ll l Rulemaking Options y)

1. Deny the Petition. The petition could be denied on the basis that there are sufficient provisions within 20.1301(c) to allow case-by-case use of the 0.5 rem (5 mSv) annual dose limit for "specified visitors" of radiation therapy patients. In fact, the NRC recently granted an t[.

amendment request to the University of Cincinnati to apply the 0.5 rem (5 mSv) dose limit to F care givers of radiation patients as specified by the authorized user physician. . , ,

e The advantage of option 1 is that it does not require govemment resources for rulemaking. I; ti '

The disadvantage of this option is that access to radiation patients by care givers would be di constrained by the 0.1 rem (1 mSv) dose limit of 20.1301 unless prior authorization were ['

requested by the licensee and granted by the NRC. The process to obtain authorization to jj operate up to an annual dose limit for an individual member of the public of 0.5 rern (5 mSv) can H' be time consuming and impose a financial burden on the licensee. .-r . -

3 The cdvantage of option 2 is that it would relieve the licensee of the administrative burden and exp:nse of requesting, on a case-by-case basis, NRC authorization to exceed the 0.1 rem (1 mSv) dose limit to permit closer contact between care giver and patient. ~ Records of individual exposures and documentation of instructions to minimize radiation exposure would enable the NRC to verify that liceasees are' complying with the new provision. The patient would benefit from the less restrictive visits and additional physical and emotional support provided by care . .

giv;rs. -

The tre disadvantages with option 2. First, owing to the fact that no application for a license r cm:ndment r eed be made, a greater number of family members and care givers may be l permitted to be in close proximity to radiation diagnostic and therapy patients. Consequently, ' Y th:se care givers would be subject to increased radiation exposure and an increased, albeit s sm ll, health risk. Second, the licensee would be burdened by the requirements to badge those cars givers who might exceed the 0.1 rem (1 mSv) dose limit, maintain exposure recorcs for ,.

each badged care giver, and document that ALARA guidance was provided. Third, the NRC j E

clso would be burdened with the requirement to inspect licensee records documenting care -

giv:r badging, exposure, and ALARA instruction. g

3. Grant the Petition Without Exposure Monitorino. The total effective dose equivalent  ;

anticipated for virtually all care givers of radiation patients will be significantly less than 0.5 rem L (5 mSv), especially if the care givers follow the ALARA guidance. Consequently,it does not (

app ar that the petitioner's suggested measures, beyond basic ALARA instruction, warrant the cdministrative burdens associated with badging care givers. Licensees already demonstrate , S compliance with the public dose limit by maintaining records of dose rates in unrestricted areas; , 2

each care giver. In addition to amending 20.1301,9% 35.315 and 35.415 would be amended' to r: quire licensees to obtain and document voluntary informed consent from care givers who g [f ~

may receive a total effective dose equivalent of up to 0.5 rem (5 mSv). Licensees would be required to document that the care giver received ALARA instruction. Section 20.1003 wouid be ( g, .'f cm:nded to include a definition of care giver. <

$ The advantages and disadvantages of this option are similar to those described for option 2 6 I cxcept that licensees would not be burdened with monitoring and recording individual external  ;

_ exposures or with associated reporting requirements. The responsibility for not exceeding the y 0.5 rem (5 mSv) exposure limit would rest with the licensee even though the licensee is reliant t t

t upon the care giver to adhere to ALARA guidance and time-distance restrictions,if any. ,

.E Although badging and area surveys could be used to document that the 0.5 rem (5 mSv) limit .

J w:s not exceeded,it is unlikely that badging itself would prevent an overexposure, and therefore T brdging would not be required.

cnd 35.415 (a)(2) to require the licensee to post on the door of the patient's. room a " Radioactive Materials" sign that contains the following information: (1) where and how long an adult visitor may stay in the patient's room, (2) where and how long visitors under the age of 18 may stay in tha patient's room, and (3) a list of guidelines visitors should follow to keep exposures ALARA.

] 3 Licensees would have the option to not specify the location of the visitor within the room but to cdjust the stay time calculation accordingly. No dosimetry badging of visitors would be required under this option.

Tha principle advantage of option 4 is that this attemative would alleviate the authorized user physician of the burden of determining which members of the public constitute adult patient care g

giv:rs, because responsibility for determining who can visit a radiation patient would be left g

=

cntirely to the visitor. Entering the patient's room after reading the " Radioactive Materials" sign 9 would constitute informed consent, receipt of ALARA guidance, and acceptance of time-distance 4 , M r:strictions. This would relieve the licensee of the burden of documenting consent to potentially r:ceive a radiation exposure that exceeds the 0.1 rem (1 mSv) public dose limit and providing ]. -f ALARA instruction and exposure restrictions to each visitor. This option also would reduce th number of inspection requirements and eliminate.the need for licensees to collect information from visitors to radiation patients. Although badging would be useful to document that the 0.5 y)

Nf g

=g r:m (5 mSv) limit was not exceeded, it is unlikely that badging itself would prevent an p *h hg 4 ovarexposure, and therefore would not be required. $th p The disadvantage of option 4 is that there would be no way to either ensure or document that 8 -

the care giver read or understood the potential consequences of being in close proximity to the d h  !

patient, or understood the ALARA instrmion. Hence, there is a possibility that individuals could Y }

Proferred Option i

i r.

f i ig Option 3 is the preferred option. Option 3 is consistent with ICRP, IAEA, and NCRP guidance in that it would allow voluntarily exceeding the public dose limits to assist in medical care.

informed consent to the exposure as well as to provide ALARA guidance. In addition, the licensee would be required to document that the care giver provided informed consent about i

places a financial burden on the license just to request the license amendment. The time required to obtain authorization to exceed the public dose _ limit occurs when both the patient and care givers are likely to receive the greatest benefit from such access.

Option 2 is an acceptable option. It permits closer contact between care givers and patients if p f the individual and the treating physician agree that the potential increase in risk is justifiable. Wyk However, the licensee anditimposes imposes an additional an increased burden inspection burden on theof badging, NRC.'

P,.h dose limit. Further, because this option, unlike options 2 and 3, would remove the licensee's active control to permit access by members of the public to radiation, it is inconsistent with current practice that reflects the NRC's position that the fundamental dose limit for. individual h

members of the public is 0.1 rem (1 mSv), and that higher doses, while appropriate in some circumstances, are not to be permitted routinely.

Office of General Counsel Legal Analysis The proposed rulemaking revisions would address the problem identified by the petition for rulemaking. These revisions are consistent with ICRP,IAEA, and NCRP guidance. OGC has not identified any basis for a legal objection to the rulemaking. The rule does not affect reactors, I;,*;

therefore the rule does not constitute a backfit under 10 CFR 50.109. An environmental h 4

assessment must be prepared for this rule in compliance with 10 CFR 51.21. There are new information collection requirements in this proposed rule, therefore, to comply with the n Paperwork Reduction Act of 1980, an analysis must be prepared and the information collection {j requirements must be submitted to the Office of Management and Budget for approval. The e final rule must be evaluated for compliance with the Small Business Regulatory Enforcement R Faimess Act of 1996, i b

Since the proposed rulemaking plan would address resolution of PRM-20-24, the staff will need N to assure that the appropriate procedural actions are taken to close the actions associated with I that petition. These actions include specifically granting or denying the petition for rulemaking, [

either in the Federal Register notice associated with the rulemaking or in a separate Federal Register notice, and informing the petitioner of the NRC's decision. The detailed procedures for '

responding to the rulemaking petition are contained in Part 11 of the Regulations Handbook .

(NUREG/BR-0053, Rev.3). e t

Major Rule This rulemaking does not constitute a major rule.

Supporting Documents Ne'eded '

A Regulatory impact Analysis, Environmental Assessment, and an Office of Management and Budget clearance package will need to be developed in support of this rulemaking.

Issuance by Executive Director for Operations or Commission This rulemaking would not fall within the authority delegated to the EDO to issue this rule in -~

accordance with paragraph 0213 of Management' Directive 9.17. It, therefore, will be forwarded to the Commission for approval. i Resources Needed to Complete Rulemaking p; ..

Tha estimated resources to complete this rulemaking would be about 0.5 staff years.

Approximately 60 percent of this effort would come from RES and about 40 percent divided f:

among NMSS, OSP, OE, and OGC. 7i G '

In addition, contractor support funding of S50,000 would be used to assist in developing the @?

Regulatory impact Analysis. These resources are included in the current budget. No additional .
