At the very least this does show that the use of the Full Body suits is more or less standard practice with the X37-B.
Is that first photo a pre-mission service? Or maybe just a time far between missions when there would be no fuel? I'm surprised that with such a classified mission they would let so many people around it.
If the theory that those are Geiger Counters is true, then it does make one wonder what the cargo is. Could just be for any radiation it might acquire in space flight though.

Hydrazine is highly toxic and dangerously unstable, especially in the anhydrous form. According to the U.S. Environmental Protection Agency: Symptoms of acute (short-term) exposure to high levels of hydrazine may include irritation of the eyes, nose, and throat, dizziness, headache, nausea, pulmonary edema, seizures, coma in humans. Acute exposure can also damage the liver, kidneys, and central nervous system. The liquid is corrosive and may produce dermatitis from skin contact in humans and animals. Effects to the lungs, liver, spleen, and thyroid have been reported in animals chronically exposed to hydrazine via inhalation. Increased incidences of lung, nasal cavity, and liver tumors have been observed in rodents exposed to hydrazin
The original X-37 was to feature an AR-2/3 engine for maneuvering and deorbiting, which uses Hydrogen Peroxide and JP-8 as oxidizer and fuel. Later the propulsion system has been changed to a hypergolic nitrogen tetroxide / hydrazine version with a robust propellant load for maneuvering in space and for the deorbit burn.
