There are no 'scientific facts' as stated by Stephen Reinhart (Nick Adams) in this movie, that radiation causes mutations in plants and animals. Only numerous suppositions and theories, such as those surrounding The Chernobyl Disaster.
When Rheinhart gets off the train, you can see that its very cold because his breath comes out as condensation.
However, there are people sitting outside drinking at the the local pub, the grocer has fruits and vegetables outside on a stand, and the bicycle repairmen is working outside in shirtsleeves. None of this would have happened in the weather as shown.
The crater left by the meteor looks like a quarry hole, not an impact crater.
Additionally, there are trees right up to the edge of the crater, which is not possible after an object that size has struck the ground, There should have been no trees for some distance around the crater.

When Nahum is fully mutated, it is clear that he is being portrayed by a stunt man wearing a silvery mask and gloves. These don't coincide with the appearance of any of the other mutations. The blurring effect used to indicate his radioactivity spills over onto his surroundings, particularly as he chases Stephen around the room at the film's climax.
When the stranger arrives, looking to get to "the Witley Estate", can't get a taxi, hire a car or even a bicycle, several times he asks directions which he never gets, told the only way he'll ever get there is to walk, he wanders off with no directions and yet in the absence of any signposts arrives at a locked front gate which has NO name (no "Witley Manor") but only "Keep Out" signs which he proceeds to get around and into the grounds.
The bicycle shop proprietor raises an arm to indicate the direction, but after that there are branched off roads, where either direction could be the correct one, and he even walks across rough ground with no path, but somehow manages to reach the house he's looking for.
