Yes, even though they do emit ionizing radiation. The amount of radiation emitted from a smoke detector is about 1 hundredth of a millirem per year. The background radiation from radioactive isotopes in the ground is about 300 millirem per year. So the ground your standing on right now is exposing you to more radiation then your smoke detector ever will.
Many newer CO detectors and smoke detectors now come with an integral battery that cannot be replaced. This is because fire inspectors were discovering massive non-compliance with replacing CO detectors at 7 years and smoke detectors at 10 years. Since people falsely assumed that simply replacing the batteries was "good enough", not being able to replace them any more forces them to buy new ones instead.

It will depend on both the location of the rented property and the rental terms. In Ontario Canada, there is now a legal requirement for smoke detectors to be installed on each floor of a property, but this condition may not apply in other jurisdictions. The occupants of a rented single family home are expected to install smoke detectors themselves. However, for any multi-family property, the landlord is responsible for installing them. The specific requirements can be obtained by checking with the local Fire Department.
