Sherlock Holmes sometimes said that Dr. Watson saw, but did not observe. The same could be said for Kirk, Spock, Sulu and the other members of the landing party to Omicron Ceti Three.
In "This Side of Paradise" the Enterprise heads for Omicron "Mira" Ceti III to - I'm not sure what, maybe investigate and record how the colonists must have died years ago from the Berthold rays emitted by the star, pick up personal effects and maybe bodies for their relatives, etc.
And later:
When they beam down:
I think that they shouldn't have been surprised to find the colonists alive.
The buildings certainly look like they had been assembled by carpenters probably taking more than a week. The area looked well tended. And they materialized on a lawn or field with short grass a few inches high. I've mowed far too much grass to expect that grass would naturally stop growing at such a height. That grass looked like it had last been mowed a week or two earlier.
They should have been startled and said that the colonists must be alive for the grass to look so recently mowed.

KIRK: Mister Spock, there were one hundred and fifty men, women, and children in that colony. What are the chances of survivors?
SPOCK: Absolutely none, Captain. Berthold rays are such a recent discovery. We do not yet have full knowledge of their nature. It is known, however, that living animal tissue disintegrates under exposure. Sandoval's group could not have survived after three years.
KIRK: And what about us? Can we afford to send people to the planet's surface?
SPOCK: The breakdown of tissue does not develop immediately. We can risk a limited exposure.
And later:
SPOCK: Captain, this planet is being bombarded by Berthold rays, as our reports indicated. At this intensity, we'll be safe for a week if necessary. But
When they beam down:
(The group beam down into a farm, complete with wooden fence and a tarmacadamed paths. There are clap-board buildings and even a stable block.)
KIRK: Another dream that failed. There's nothing sadder. It took these people a year to make the trip from Earth. They came all that way and died.
ELIAS: Hardly that, sir. Welcome to Omicron Ceti Three. I'm Elias Sandoval.
