Microphones of this nature are designed to pick up your speaking voice while blocking out noise. I'm not exactly sure whether or not this would be a great vocal mic, especially if you are going to be screaming into it. Generally, proper operating procedure is to not scream into the mic.
Radios often have a mic gain control to enhance sensitivity.
These types of microphones sometimes require power that is usually provided by the radio and use multi-pinned connectors which perform functions like powering and enabling buttons on the mic to scan and other things. With this in mind, I'm not sure how easy it would be to wire for general audio equipment use, but I'm sure it could be done. I am aware that people sometimes use regular audio mics and wire them to be used with radios. Communications microphones generally operate with a lesser frequency response but offer superb quality for radio communications needs....not exactly ideal for vocal performances.
One thing that you can consider is buying a regular vocal mic, and wiring a push-to-talk footswitch to it.
You might be able to find said footswitches on:

Heil also makes great radio mics, with push-to-talk functions.
Most CB radio mics can also be wired to support user built echo circuits. About every trucker from here to Alaska is unintelligible with these circuits activated. Some mics have this already built in. Cobra has a line like these often times featuring redneck iconography.
Also, consider that the PTT buttons are often sensitive, and pushing them hard or releasing them hard will generate clicks and wear out fast. Not something that you want to consider in the heat of a passionate and dramatic vocal performance. No vigorous thumb wrestling moves on the hammer there.
Hope this helps a little. My knowledge of the nuances of mobile mics is limited.
I have a feeling there are some people here with the knowledge..
