Uncheck the checkbox when click on other radio button

In this code there are two radio button and each consist of some information but in the first radio button there is a one checkbox i.e input type="checkbox" so the issue is if I click on first radio button and inside that I also click on checkbox it works fine but when I click on other radio button the checkbox should get unchecked similarly When I click on first radio button the checkbox should get unchecked until I click on it
