Here are some examples that you can try

<apex:inputField> example

VF Page
<apex:page standardController="contact" extensions="radioActionCtrl"  >
    <apex:form >
        <apex:selectRadio >
            <apex:actionSupport event="onchange" action="{!changeInputState}" rerender="opPanelName"/>
            <apex:selectOption itemValue="" itemlabel="Option1"/>
        <apex:outputPanel id="opPanelName">
            <apex:inputField value="{!contact.firstName}" id="NameInput" required="false"/>
                document.getElementById('{!$Component.NameInput}').disabled = {!disableInput};

Controller Extension
public class radioActionCtrl {
    public Boolean disableInput {get; set;}
    public radioActionCtrl(ApexPages.StandardController controller) {
        disableInput = true;
    public void changeInputState(){
        disableInput = false;

<apex:inputText> example
<apex:page controller="dynSelect">
    <apex:form id="form">
        <apex:selectRadio value="{!selectedOption}">
            <apex:actionSupport event="onchange" rerender="form" />
            <apex:selectOption itemValue="Yes" itemLabel="Yes" />
            <apex:selectOption itemValue="No" itemLabel="No" />
        <apex:inputText rendered="{!selectedOption='Yes'}" />

You can do this with jquery as well. Try it yourself
