A wet column generator is equipped with all of the following parts except?

A wet column generator is a device used in nuclear medicine to produce radiopharmaceuticals for diagnostic imaging. The correct answer is based on the fundamental components required for the operation of a wet column generator.

An alumina column is essential as it serves as the substrate where the radioisotope is retained and extracted. The lead shield is necessary to protect personnel and the environment from radiation exposure, as many of these generators produce radioactive materials. A saline supply is crucial because it is used to elute the radioisotope from the alumina column, facilitating its preparation for use in imaging procedures.

The charging port is not a standard component within a wet column generator setup. In fact, wet column generators typically do not require a charging mechanism because they are self-contained units designed for continuous operation without the need for a separate charging input. Therefore, the absence of a charging port aligns with the typical design of a wet column generator, making it the correct answer in this context.
