A mantle field is localized according to the patient's data in an inhomogenous Alderson phantom. After having established the irradiation scheme, the dose distributions measured in the Alderson phantom are compared with those measured and calculated in an homogenous water phantom. The possible side effects of this irradiation technique can be assessed on the basis of the radiation exposure of heart, lung and spinal marrow. The dose differences found on the central ray are within the margin of error amounting to 5 to 10% which is indicated in the calculation program. In case of a total reference dose of 40 Gy, the radiation exposures of heart and lung do not reach the tolerance limit. A spinal marrow dose of 50 Gy is found in the upper neck marrow. In case of an exact therapy planning, a sufficient dose can be directed to the Waldeyer's tonsillar ring.

D003037	Cobalt Radioisotopes	Unstable isotopes of cobalt that decay or disintegrate emitting radiation. Co atoms with atomic weights of 54-64, except 59, are radioactive cobalt isotopes.	Radioisotopes, Cobalt
D005720	Gamma Rays	Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during NUCLEAR DECAY. The range of wavelengths of emitted radiation is between 0.1 - 100 pm which overlaps the shorter, more energetic hard X-RAYS wavelengths. The distinction between gamma rays and X-rays is based on their radiation source.
