Total skin electron irradiation is a technique used primarily in the treatment of skin conditions such as mycosis fungoides or other skin malignancies. The appropriate selection of electron beam energy is crucial to ensure that the dose delivered adequately covers the entire skin surface while minimizing exposure to underlying tissues.

Low energy electron beams, typically in the range of 3 to 6 MeV, are ideally suited for this purpose. These lower energy beams have a limited penetration depth, which allows them to effectively treat superficial lesions while sparing tissues deeper in the body from excessive radiation exposure. The choice of low energy is particularly important because higher energy electron beams would penetrate too deeply, potentially increasing the risk of undesired side effects in underlying tissues and organs.

Thus, the selection of low energy beams for total skin electron irradiation ensures that the treatment effectively targets the skin while prioritizing the safety of surrounding structures. This is why the option reflecting low energy beams around 3 to 6 MeV is the correct choice in this context.
