Tandem systems, each formed by a pencil ionization chamber with and without a specific
covering, were developed and tested in standard radiation beams. These systems were …

A pencil-type ionization chamber, developed at Instituto de Pesquisas Energéticas e
Nucleares (IPEN), was characterized with the objective to verify the possibility of its …

Medical diagnostic equipment, like diagnostic radiology and mammography require a
dosimeter with high accuracy for dosimetry of the diagnostic X-ray beam. Ionization …

An extrapolation minichamber was developed for measuring doses from weakly penetrating
types of radiation. The chamber was tested at the radiotherapeutic dose level in a beam from …

A new monitor ionization chamber was developed at Instituto de Pesquisas Energéticas e
