Claim 39:
40. A brachytherapy device, comprising:
a probe adapted for being at least partially introduced into a body of a subject;
particles of Radium-224 retainably embedded on or beneath a surface of the probe, in a manner ensuring that the particles of Radium-224 remain in the probe while a therapeutic dose of decay chain radionuclides and alpha particles of said particles of Radium-224 leaves the surface; and
particles of Thorium-228 retainably embedded on or beneath the surface of the probe, in a manner ensuring that the particles of Thorium-228 remain in the probe while a therapeutic dose of decay chain radionuclides and alpha particles of said particles of Thorium-228 leave the surface,
wherein an activity level of the particles of Thorium-228 is lower than 50% of an activity level of the particles of Radium-224 in the device.
