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 application in radiation field mapping procedures. The characterization tests were evaluated, and the results were satisfactory. The results obtained for the X radiation field mapping with the homemade chamber were compared with those of a PTW Farmer-type chamber (TN 30011-1). The maximum difference observed in this comparison was only 1.25%, showing good agreement.
► A new ionization chamber was made and tested for radiation field mapping.
► This ionization chamber was made using only accessible low cost materials.
► The operational tests were made and the results were within the recommended limits.
► The field map was compared with a commercial chamber presenting a 1.25% difference.
► Our chamber presents potential for assurance reliability in calibration procedures.
