§ 175.16 Surveys and Monitoring.
RCNY § 175.16
Each registrant must conduct surveys to comply with this Article to evaluate the magnitude and extent of radiation levels and potential radiological hazards.
(a)The registrant must ensure that instruments and equipment used for quantitative radiation measurements, for radiation survey purposes, are calibrated at intervals not to exceed 12 months for the radiation measured, except when a more frequent interval is specified in this Article.
(b)All personnel dosimeters, except for direct and indirect reading pocket ionization chambers and those dosimeters used to measure the dose to any extremity, that require processing to determine the radiation dose, must be processed and evaluated by a dosimetry processor: (1) holding current personnel dosimetry accreditation from the National Voluntary Laboratory Accreditation Program of the National Institute of Standards and Technology; and (2) approved in this accreditation process for the type of radiation or radiations included in the National Voluntary Laboratory Accreditation Program that most closely approximates the type of radiation or radiations for which the individual wearing the dosimeter is monitored.
(c)The registrant must ensure that adequate precautions are taken to prevent a deceptive exposure of an individual monitoring device.
(d)No registrant shall remove an exposure from an individual's exposure record without prior authorization from the Department. To remove an exposure from an individual's exposure record, the registrant must provide the following documentation to the Department: (1) a letter to the Department indicating the person whose exposure is to be removed along with an investigation into the possible causes for the exposure and a signed note from the individual concurring with the removal of the exposure; and (2) a copy of the individual's personnel monitoring report along with the investigation the personnel monitor vendor conducted of the exposure. For occurrences where the personnel monitor vendor indicates that a static exposure occurred on the personnel monitoring report sent to the registrant, the latter investigation is waived.
