A Highly Focused Treatment for Brain Cancer Relies Upon _____________________

Question

A highly focused treatment for brain cancer relies upon _____________________. A)¹²⁵I nuggets hemisperically arranged around the tumor, emitting convergent alpha particle beams which create the so-called alpha knife. B)⁹⁹Tc nuggets hemisperically arranged around the tumor, emitting convergent X ray beams which create the so-called X ray knife. C)⁶⁰Co nuggets hemisperically arranged around the tumor, emitting convergent gamma ray beams which create the so-called gamma knife. D)⁹⁹Mo nuggets hemisperically arranged around the tumor, emitting convergent beta ray beams which create the so-called beta knife.

Accepted Answer

The highly focused treatment for brain cancer is called the gamma knife, which utilizes hemisperically arranged Co-60 nuggets to emit convergent gamma ray beams. Option A and D are not accurate regarding the elements used and the type of radiation emitted, and option B mentions X-rays, which are not typically used in the gamma knife procedure.
