Does it matter which Radionuclide?

Emission type: Photon radiation: +++ (penetration) Electrons: - - - (dose near the source; used in endovascular)

Emission energy: High energy photons useful in temporary implants, at the expense of higher shielding costs. Low energy photons useful in permanent implants, with limited radiation to the surrounding of the patient.
