A total of 20 oral presentations plus a number of posters addressed a wide variety of subjects related to the study or use of radiation in physics. Talks were given on fundamental physics, instrument development, applications in the natural environment, material characterization, industry and scientific policy, among others.</font></p>     <p align="justify"><font face="verdana" size="2">We would like to recognize the exceptional performance of the local organizing committee and officials of the Universidad de Guanajuato, whose generous support and efforts on behalf of the symposium made its success possible.</font></p>     <p align="justify"><font face="verdana" size="2">The Symposium was also made possible thanks to the financial support of our sponsors: <i>Consejo Nacional de Ciencia y Tecnolog&iacute;a </i>(CONACYT), <i>Subsecretar&iacute;a de Educacion Superior e Investigaci&oacute;n Cient&iacute;fica de la Secretar&iacute;a de Educacion P&uacute;blica </i>(SESIC&#150;SEP), <i>Division de F&iacute;sica de Radiaciones, Sociedad Mexicana de F&iacute;sica </i>(DFRSMF) <i>Universidad de Guanajuato </i>and <i>Universidad Nacional Autonoma de M&eacute;xico </i>(UNAM).</font></p>     <p align="justify"><font face="verdana" size="2">Finally, the organizing committee would like to thank all the participants whose contributions made this Symposium a success. We look forward to their support of future international symposia on radiation physics in M&eacute;xico and encourage participation of researchers and scientists in this field.</font></p>     <p align="right"><font face="verdana" size="2">&nbsp;</font></p>     <p align="right"><font face="verdana" size="2">Juan Aspiazu    <br> Efrain Ch&aacute;vez    ]]></body>
