In Star Trek TOS S03:E07 Day of the Dove it is said to be dangerous to beam intra-ship.

Yet in TNG it is common. We even see intra-ship beaming in Star Trek Discovery S1:E08 Si Vis Pacem, Para Bellum.

My question is: Why would they say in TOS it was dangerous to beam intra-ship?

    Because the technology in TNG is a hundred years more advanced?

  • And Discovery was produced 50 years after TOS

    TNG is 100 years later. Technology has changed. Memory Alpha give the launch date of the Enterprise NCC 1701 as 2245 while it says that in 2256 Discovery was still considered "new.. and equipped with some of Starfleets most advanced technologies" as in, it's better than a 10 year old heavy cruiser.

    When a hostile alien controls the ship as in "Day of the Dove", it may be able to divert the transporter beam.

As far as canon (excluding Discovery, as I haven't watched it yet), Transporter technology was much more advanced in the 24th century than in Kirk's time. They are able to beam around the ship (as the plot desires).

I have no clue why they would be able to do that in Discovery
