Abstract: <span style="font-size:10.0pt;font-family: " times="" new="" roman";mso-fareast-font-family:"times="" roman";mso-bidi-font-family:="" mangal;mso-ansi-language:en-us;mso-fareast-language:en-us;mso-bidi-language:="" hi"="" lang="EN-US">Radio frequency (<i style="mso-bidi-font-style:normal">RF</i>) driven ion sources are used in various scientific applications like neutral beam injection systems for fusion reactors, particle accelerators, neutron generator and neutron spallation source. In BARC, a <i style="mso-bidi-font-style:normal">dc</i> accelerator based 14 MeV neutron generator uses <i style="mso-bidi-font-style: normal">RF</i> type ion source. This ion source uses an indigenously developed <i style="mso-bidi-font-style:normal">RF</i> amplifier system, which capacitively couples (via two external electrode rings) the <i style="mso-bidi-font-style: normal">RF</i> power at 100 MHz to deuterium gas filled <i style="mso-bidi-font-style: normal">RF</i> ion source assembly to generate deuterium plasma. The <i style="mso-bidi-font-style:normal">RF</i> radiation (non- ionizing radiation) emanates from the capacitively coupling in addition to very minor <i style="mso-bidi-font-style:normal">RF</i> radiations from the amplifier assembly itself. This radiation was measured at various locations within the neutron generator facility and was, then analyzed from safety point of view and compared with international standards for <i style="mso-bidi-font-style:normal">RF</i> radiation. It was observed that the measured <i style="mso-bidi-font-style: normal">RF</i> radiations are within the limit and do not pose any hazard for equipment or personal safety. This paper describes in detail the measurements and their analysis.</span>
