To carry out these measurements, several thermoluminscent dosimeters (TLD's) were used to measure the expose. In this procedure, very few information of direction where the radiation came from is available. A vague supposition about the direction from where the radiation came from could be inferred only by evaluation of multiple dosimeters displaced at entire region of monitoring, but this demand to much effort or sometimes become impractical for certain situations. In this work, a single device is used to provide information about the direction from where the radiation came through. This device is called directional dosimeter (DD)[1]. Using more than one DD it is possible to reduce the uncertainty of the measurements and determine the radiation source position. The DD basically consists of a regular solid with high effective atomic number, where one TLD is positioned at each face. The DD allows evaluating the environmental exposure and the direction of the radiation by a simple vector sum. At each face of the DD, it is associated an orthogonal vector, and modulus of this vector represents the correspond exposure measured by the TLD. The direction of the radiation source is the sum of these faces vectors. The prototype used in this work was a lead cube with six TLDs of CaSO4:Dy/Teflon. The TLDs have high sensibility and are already used in area, environmental and personal monitoring. The measurements had shown the correct environmental exposure and a good indication of the radiation direction.Artigo IPEN-doc 12161 Assessment of the ambiental exposure at IPEN using CASOsub(4):Dy detectors with different filters combination2007 - CAMPOS, VICENTE de P. de; ROCHA, FELICIA D.G.; RODRIGUES, LETICIA L.C.Dissertação IPEN-doc 11253 Desenvolvimento e avaliação de um novo porta detector/filtro para monitoramento termoluminescente com CaSOsub(4):Dy/PTFE2005 - CAMPOS, VICENTE de P. deArtigo IPEN-doc 08422 An approach for the efficiency calibration of whole body counters2001 - VENTURINI, L.; CAMPOS, V.P.; BERTI, E.A.R.
