Anything transmitted by radio will travel through space forever.
I believe James Whale was sacked from Talk Radio for promoting Boris Johnson in the London Mayoral elections. All radio presenters should remain impartial at all times
Many of them have their own emergency generators, ready to take over if the commercial power fails.
Radio Radio was created in 1977.
No, they will eventually find ways out of your body. These isotopes are injected for certain radiation treatments at the doctors office or hospital such as: xray, catscan, mri, etc. Those that don't leave the body eventually decay and become inert, just as any other radioactive substance does.

radio-isotopes
Radio active isotopes are unstable isotopes of an element as there neutron number degenerate by emission of light or medium.

Iodine is safe to be injected in the body for medical imaging procedures because it is a non-toxic essential element that the body needs for thyroid function. It is rapidly cleared from the body through the kidneys after being used for imaging, reducing the risk of accumulation and toxicity. However, allergic reactions or adverse effects can occur in some individuals.
All radio-actives isotopes disappear by radioactive decay.
There are a lot more than 2 radio active isotopes... To answer this question a naturally or created radioactive element needs to be mentioned.

The use of nuclear energy in civilian society is to generate electricity. In the military it is to make bombs (and hopefully not use them). There are also some uses in medicine where radio isotopes can be used for diagnosis and treatment. These isotopes are produced by irradiation in low power reactors which enable short lived radio isotopes to be obtained as required.
TV going digital has nothing to do with AM radio. AM & FM radio will remain the same.
