Okay Thanks

True, you have to enable interrupts globally for the peripheral in question. Sorry for missing that...
The code Erlend posted should work fine :)

To do that I think this will do NVIC_ClearPendingIRQ(RADIO_IRQn); NVIC_EnableIRQ(RADIO_IRQn);

Don't you also need to enable the radio IRQ line or something? (I think what is asked is how to do this)

If you need the interrupt handler to respond to multiple events you need to check each event before calling the corresponding code (and then clearing the event afterwards).

This is a very common snippet in the Nordic libraries, and could look something like this:

if (NRF_RADIO->EVENTS_READY && (NRF_RADIO->INTENSET & RADIO_INTENSET_READY_Msk))
{
    NRF_RADIO->EVENTS_READY = 0;
    
    ....
}

If you are looking to do a proprietary RF protocol I would suggest having a look at the ESB or Gazell libraries available in the SDK. Then you don't have to spend time implementing things such as packet buffering, acknowledgements, auto retransmit and so forth.
