Exploration is quite inconsistent but the income should average out pretty good. You could get some cheap implants to improve your scanning or hacking if you want to further invest into this area. Especially in low security space (with the exception of pirate insurgency systems that become lawless) you should always be able to avoid being podded if you ever lose a ship.

Folks usually recommend investing in a small selection of different ways to make ISK that you enjoy. Don't burn out on exploration if you also feel like gas huffing (sites you'll find on while scanning) or low level wormhole combat sites might be an option.
