Answer this question… Radiation is being released from the reactor.
A pen dosimeter is a dosimeter the size and shape of a pen. In many cases they are radiation quartz fiber dosimeters made during the cold war for civil defense workers in the case of a nuclear attack. Of these the CD V-742 is the most common with over three million being produced.

There are different kinds.The thermoluminescent dosimeter has a crystal that stores energy when exposed to radiation and then emits light when heated.An OSL (optically stimulated luminescence) dosimeter works in a similar manner, except that a laser is used to stimulate the light emission instead of heat.To measure neutron radiation, a commonly used dosimeter uses solid state nuclear track detectors (SSNTDs). For example, a small square of CR-39 (the same plastic used in many lenses for glasses) develops latent damage tracks as the neutrons collide with protons in the plastic. These latent tracks are later developed using a caustic solution, e.g., sodium hydroxide solution and the developed tracks are counted using a microscope.Hopefully someone else can add how other types of dosimeters work by improving this answer for you.
Fallout is a mixture of:fission productsdirt picked up by the updraft into the mushroom cloudneutron activated isotopes of normally non-radioactive parts of the bomb and nearby objectsoxides of unfissioned uranium and/or plutonium from the bombetc.

A radiac detects nuclear radiation. There are many types of radiac, some are: Geiger counter, ionization survey meter, scintillation counter, film badge dosimeter, electroscope dosimeter, electrometer, drift meter, cloud chambers, etc.

it was first noticed with the nuclear bomb tests.

The term "Broken Arrow" is used to indicate a nuclear accident involving a nuclear weapon that does't pose the threat indicated. The term "excursion" (as in nuclear excursion) or "criticality accident" is applied to a nuclear reactor or nuclear material accident, respectively.
Most people would use the abbreviation 'sub.' The US Navy uses the prefix SS to indicate a submarine. If it is SSN, it would indicate a Nuclear Powered submarine and SSBN would be a ballistic missile nuclear powered sub.
No. Define "blow up". Power plants have malfunctions that can kill people, unrelated to nuclear fuel. Nuclear elements can be arranged to blow up but you have to get everything exactly right. More danger exists from exposure to the fuel, if it has been activated.

None of those indicate a USN officer rank. Some might indicate some enlisted man's rank...but "SN" is often used to indicate SERIAL NUMBER and after the Vietnam War, it meant "SOCIAL SECURITY NUMBER." Today often termed SSN; but those letters can also mean NUCLEAR SUBMARINE (SS=Sub, N=Nuclear).
