(19) Treatment modalities included: partial temporal bone resection, subtotal temporal bone resection, total temporal bone resection, radical mastoidectomy followed by radiation therapy, radiation therapy alone, and chemotherapy.
(20) In addition, a new dosage concepts has been introduced on the basis of the effective dose on the lines of the recommendations by the IRCP; as a result, the definitions of radiation protection areas and of dosage limit values had to be revised and reworded.
Transmittance
Definition:
(n.) Transmission.
