Question 1

Is it supposed to be ticking? It ticks twice every couple of seconds. Has been doing this nonstop for months

Accepted Answer

To add to the other responders to your question, the quiet ticking has nothing to do with actual detection of radiation.  Should your Nukalert pick up a significant amount of penetrating gamma radiation, it will respond with louder audible chirps about the volume of a human voice talking.  This detector is designed for 'wartime' use to scout out medium to fairly high (and immediately dangerous) levels of nuclear radiation, not detect any low level background radiation.  I hope that helps!

Question 2

Does this detect high nuclear activity in time to seek shelter or medical assistance? I'm wondering if this would be a good bug out alarm.

Accepted Answer

It will. I recently had a nuclear stress test. I keep mine hanging at my desk. I kept hearing this rapid ticking sound, and it was a minute before I figured out it was my NukAlert. So yeah, it will let you know if something is up.

Question 3

Where can I get the batteries replaced?

Accepted Answer

The company will if you send it to them. They are suppose to lasr 10 years, of course if no nuclear incidents.The company states that if you put the device next to your ear and you don't hear the internal clicks (at about 30-60 seconds) which is normal. If you hear nothing that means the battery is malfunctioning or dead. The company states to send the device back and they will replace it within the warranty.

Question 4

I boughtt one years ago. How can I tell if the battery needs replaced, and how would I do so?

Accepted Answer

It's guaranteed to last 10 years from the time you buy it. You can't replace the battery. When it dies you buy a new one. I quests the manufacture feels that after 10 years you got your money's worth. As far as testing it. I don't know how to do that. I do know that from time to time mine makes slight ticking noises I believe from background radiation.
