React Evergreen is a popular front-end library with a set of React components for building beautiful products as this library is flexible, sensible defaults, and User friendly. Radio Component allows the user to select one option from a set or list of items. We can use the following approach in ReactJS to use the Evergreen Radio Component.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:
```
npx create-react-app foldername
```
Step 2: After creating your project folder i.e. foldername, move to it using the following command:
```
cd foldername
```
Step 3: After creating the ReactJS application, Install the required module using the following command:
```
npm install evergreen-ui
```

Project Structure: It will look like the following.

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

App.js

import React from 'react'
import { RadioGroup } from 'evergreen-ui'

export default function App() {

  const [ageGroup, setAgeGroup] = React.useState('0-10 years')

  return (
    <div style={{
      display: 'block', width: 700, paddingLeft: 30
    }}>
      <h4>ReactJS Evergreen Radio Component</h4>
      <RadioGroup
        label="Please select your Age group"
        value={ageGroup}
        options={[
          { label: '0-10 years', value: '0-10 years' },
          { label: '10-20 years', value: '0-10 years' },
          { label: '20-40 years', value: '0-10 years' },
          { label: '40-60 years', value: '40-60 years' },
          { label: 'Above 60 years', value: ' Above 60 years' },
        ]}
        onChange={e => setAgeGroup(e.target.value)}
      />
    </div>
  );
}

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start
