Radiation Control Unit

The Unit is responsible for the protection of the public from unnecessary and unhealthful exposure to radiation by inspecting radiation sources, investigating incidents involving exposure to individuals, releases of radioactive materials, sampling of air and water and monitoring the transportation of radioactive materials throughout the County. The most common source of public exposure to radiation, after natural background radiation, is exposure to medical x-rays. Reducing patient exposure and operator exposure from medical and dental x-rays to the lowest amount that is "reasonably achievable" is the Units primary function

Every X-ray machine must be registered with NYSDOH. The registration covers a two-year period. In addition to this the X-ray machine must be inspected at a frequency determined by the type of installation. Suffolk County issues a separate Certificate of Inspection, when the X-ray machine is found to be in compliance with Part 16 of the NYS Sanitary Code and the fee for inspection has been paid to the Suffolk Co Dept of Health Services. Consequently, the Certificate of Inspection expiration date does not coincide with the expiration date for the Registration.



Contact the Department at the address above or call (631) 852-5999 within 10 days of the installation to schedule an inspection of the replacement equipment.
