      The beta emission of ⁶⁰Co can probably get through over 6mm of glass. This should be plenty for phones.

      But also

      ⁶⁰Co undergoes beta decay to an excited state of the stable isotope nickel-60 (⁶⁰Ni), which then emits two gamma rays […]

        Even if it got blocked, there’s a fair bit of metal in a phone which will produce Bremsstrahlung under beta radiation. Obviously that’s only going to hit your face, not the sensor.
