(1) This section establishes standards for protection against ionizing radiation resulting from the use of radiation machines.(2) The requirements in this section are designed to control the receipt, possession, use, and transfer of radiation machines by any person so the total dose to an individual, including doses resulting from all sources of radiation other than background radiation, does not exceed the standards for protection against radiation prescribed in this section. However, nothing in this section shall be construed as limiting actions that may be necessary to protect health and safety in an emergency. A person who receives, possesses, uses, owns, or acquires radiation machines prior to receiving a certificate of registration is subject to the requirements of this chapter.(b) Scope. (1) Except as specifically provided in other sections of this chapter, this section applies to persons who receive, possess, use, or transfer radiation machines. The dose limits in this section do not apply to doses due to background radiation, to exposure of patients to radiation for the purpose of medical diagnosis or therapy, to exposure from individuals administered radioactive material and released in accordance with this chapter, or to voluntary participation in medical research programs. However, no radiation may be deliberately applied to human beings except by or under the supervision of an individual authorized by and licensed in accordance with Texas' statutes to engage in the healing arts.(2) Registrants who are also licensed by the agency to receive, possess, use, and transfer radioactive materials must also comply with the requirements of § 289.201 of this title (relating to General Provisions for Radioactive Material) and § 289.202 of this title (relating to Standards for Protection Against Radiation from Radioactive Material).(c) Definitions.

The registrant shall use, to the extent practical, procedures and engineering controls based upon sound radiation protection principles to achieve occupational doses and public doses that are ALARA.(m) Occupational dose limits. (1) The registrant shall control the occupational dose to individuals to the following dose limits. (A) An annual limit shall be the TEDE being equal to 5 rems (0.05 Sv).(B) The annual limits to the lens of the eye, to the skin of the whole body, and to the skin of the extremities shall be: (i) an LDE of 15 rems (0.15 Sv); and(ii) an SDE of 50 rems (0.5 Sv) to the skin of the whole body, or to the skin of any extremity.(C) The annual limits for a minor shall be 10% of the annual occupational dose limits specified in subparagraphs (A) and (B) of this paragraph.(D) If a woman declares her pregnancy, the registrant shall ensure that the DE to an embryo/fetus during the entire pregnancy, due to occupational exposure of a declared pregnant woman, does not exceed 0.5 rem (5 mSv). If a woman chooses not to declare pregnancy, the occupational dose limits specified in paragraph (1)(A) and (B) of this subsection are applicable to the woman. (i) The registrant shall make efforts to avoid substantial variation above a uniform monthly exposure rate (air kerma rate) to a declared pregnant woman so as to satisfy the limit in paragraph (1) of this subsection. The National Council on Radiation Protection and Measurements recommended in NCRP Report No. 91 "Recommendations on Limits for Exposure to Ionizing Radiation" (June 1, 1987) that no more than 0.05 rem (0.5 mSv) to the embryo/fetus be received in any 1 month.(ii) If by the time the woman declares pregnancy to the registrant, the DE to the embryo/fetus has exceeded 0.45 rem (4.5 mSv), the registrant shall be deemed to be in compliance with paragraph (1) of this subsection, if the additional DE to the embryo/fetus does not exceed 0.05 rem (0.5 mSv) during the remainder of the pregnancy.(iii) The DE to an embryo/fetus shall be taken as the DE that is most representative of the DE to the embryo/fetus from external radiation, that is, in the mother's lower torso region.(iv) If multiple measurements have been made, assignment of the DDE for the declared pregnant woman from the individual monitoring device that is most representative of the DE to the embryo/fetus shall be the DE to the embryo/fetus. Assignment of the highest DDE for the declared pregnant woman to the embryo/fetus is not required unless that dose is also the most representative DDE for the region of the embryo/fetus.(v) If multiple measurements have not been made, assignment of the highest DDE for the declared pregnant woman shall be the DE to the embryo/fetus.(2) The assigned DDE shall be for the portion of the body receiving the highest exposure. The assigned SDE shall be the dose averaged over the contiguous 10 square centimeters of skin receiving the highest exposure.(3) When a protective apron is worn while working with fluoroscopic equipment used for clinical diagnostic or research purposes, the effective dose equivalent (EDE) for external radiation shall be determined as follows. (A) When only 1 individual monitoring device is used and it is located at the neck (collar) outside the protective apron, the reported DDE shall be the EDE for external radiation; or(B) When only 1 individual monitoring device is used and it is located at the neck (collar) outside the protective apron, and the reported dose exceeds 25% of the limit specified in paragraph (1) of this subsection, the reported DDE value multiplied by 0.3 shall be the EDE for external radiation; or(C) When individual monitoring devices are worn, both under the protective apron at the waist and outside the protective apron at the neck (collar), the EDE for external radiation shall be assigned the value of the sum of the DDE reported for the individual monitoring device located at the waist under the protective apron multiplied by 1.5 and the DDE reported for the individual monitoring device located at the neck (collar) outside the protective apron multiplied by 0.04.(4) The EDE determined by paragraph (3) of this subsection shall be recorded as part of an individual's dose record and will contribute to that individual's annual TEDE.(5) The DDE, LDE, and SDE may be assessed from surveys or radiation measurements for the purpose of demonstrating compliance with the occupational dose limits, if the individual monitoring device was not in the region of highest potential exposure, or the results of individual monitoring are unavailable.(6) The registrant shall reduce the dose that an individual may be allowed to receive in the current year by the amount of occupational dose received from radiation machines or radioactive materials while employed by any other person. See subsection (r)(4) of this section.(n) Conditions requiring individual monitoring of occupational dose. (1) Each registrant shall monitor exposures from radiation machines at levels sufficient to demonstrate compliance with the occupational dose limits of this section. As a minimum, each registrant shall monitor occupational exposure to radiation from radiation machines and shall supply and require the use of individual monitoring devices by: (A) adults likely to receive, in 1 year from sources external to the body, a dose in excess of 10% of the limits in subsection (m)(1) of this section;(B) minors likely to receive, in 1 year from sources of radiation external to the body, a DDE in excess of 0.1 rem (1 mSv), an LDE in excess of 0.15 rem (1.5 mSv), or an SDE to the skin or to the extremities in excess of 0.5 rem (5 mSv);(C) declared pregnant women likely to receive during the entire pregnancy, from sources of radiation external to the body, a DDE in excess of 0.1 rem (1 mSv); and(D) individuals entering a high or very high radiation area.(2) Notwithstanding the requirements of paragraph (1)(A) of this subsection, no personnel monitoring shall be required for personnel operating only minimal threat radiation machines as specified in subsection (ll)(3) of this section.(o) Dose limits for individual members of the public.
