The Geiger–Müller tube
Geiger–Müller Tube or GM Tube
The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument used for the detection of ionizing radiation. It is named after Hans Geiger, who invented the principle in 1908, and Walther Müller, who collaborated with Geiger in developing the technique further in 1928 to produce a practical tube that could detect a number of different radiation types.

You can put this dosimeter in your pocket for easy carrying.
You can hang this dosimeter on your drone, it is super lightweight and easy to fly.
You can plug the dosimeter into a USB charger and place it in a corner of your home for long-term detection of invisible rays. Just like the gas leak detection alarm machine...

Hazards of nuclear radiation
Damage to the human body and possible symptoms
For people who are not exposed to radiation in their daily work, normal natural radiation per year: mainly because the radon radiation in the air is 1000-2000 microsieverts. Radiation <100 microsieverts has no effect on human body. For radiation-related workers, the annual radiation is less than or equal to 50.000 microsieverts. A one-time exposure to 4000 mSv will cause serious damage to human functions!
Radiation dose and human response list
Dose (Rum) Reaction
5~20 May have delayed reactions; may damage chromosomes
20~100 Temporary decrease in white blood cells
100~200 Mild radiation sickness within hours: vomiting diarrhea, fatigue; decreased resistance to infection.
200~300 Severe radiation sickness reaction the symptoms are the same as above this exposure is a lethal dose, and 10%~35%ofthe exposed people die after 30 days.The LD is(10~35)/30
300~400 Severe radiation sickness damage to bone marrow and intestine;LD is (50~70)/30
400~1000 Emergency,premature death;LD is(60~95)/30
1000~5000 Emergency, death within days; LD 100/10
Irradiated Foods
Delicious 'radiation on toast' wouldn't be your first choice of breakfast but a surprising amount of everyday snacks are radioactive
Most of our foods are exposed to radiation. Most of them we bought from market and grocery have the less quantity of several key nutrients due to irradiation.
The nutrients are, Vitamin E, Thiamin Riboflavin, Pyridoxine, Vitamin B12, etc.
Irradiation is good for the health of foods to restore but somewhere harmful to the human health. Though it is not possible to avoid the irradiated foods in our daily life, We'd better know the radiation measurements and then we should try to get them organic and fresh.
Marble Radiation
Detecting radon in the renovated home and whether it exceeds the limit? Protect your health.
Marble produces a colorless, odorless gas called Radon which is a naturally occurring radioactive gas. According to the world health organization, Rn is the second largest carcinogen after smoking in lung cancer.
Radiation Alerts
Set the value and measurement, use the USB power supply all the time and hang it in a corner of your house. When the radiation level is exceeded, the Bsod geiger counter will alert you and flash a red light.
At this time you can take some measures, such as taking the appropriate amount of iodine ...
Especially for families living in seaside cities, it can be used as home nuclear survival gear. Reference 1946 bikini atoll nuclear tests and the nuclear submarine that sank underwater...
Personal Radiation Dosimeter
A dosimeter is an instrument used to measure ionizing radiation exposure (via alpha or beta particles, neutrons, gamma rays, or x-rays) in a science called dosimetry. It is an essential tool for people who work in situations where they are exposed to radiation.
Dosimeters are used to ensure that a harmful dose of radiation is not received over a given period of time. Governing bodies have standards for occupational radiation protection and control. The main goal of a dosimeter is to maintain an occupational dose as low as reasonably achievable (ALARA).
Radiation is extremely harmful to humans and can be deadly when people are exposed to high doses of radiation(Especially for pregnancy and children). Dosimeters inform and alert people when radiation levels are too high so that they can evacuate the exposure area and avoid radiation poisoning.
Near nuclear power plants
Living near a nuclear power plant does not pose a risk and according to experts, it is safe to live near a nuclear power plant. However, the only problem with nuclear power plants is the accidents linked to it which are extremely rare.

A well designed, compact and easy to use tool. Well designed. I like it very much such that I bought one for my friend as a gift.

Right out of the box I received a reading of 3.5 mill SV/h. No matter what I did the reading stayed in this range. No amount of shielding or distance of device would change this reading much. Unless a radiation source is hidden within this pen, that cannot be accurate. Is it possible it was not calibrated right. It is the gas tube defective. As far as I know no radiation source should be located within the pen. Anyone have any ideas.

Giving reasonable readings compared to other meters. Wish manual had more detail (like what's the lock icon signify?). All in all seems well built and functional so far.

I did a lot of comparison shopping against other geiger counters on Amazon and was concerned by some of the reviews on other products that none of them would be of much use, but this little guy is surprisingly fast and responsive. I can't speak to the accuracy or calibration, but it responds instantly, unlike the 30 seconds or more I've seen on reviews for other units. It's the size of a sharpy, and the display lights up making it easy to read. I'm using if for a cat who's received radio active iodine, and this is working like a charm to monitor her levels.

Works like I thought it would just a little slower to respond (40-60 sec.) but not problematic for what I am using it for.

You have no control on the threshold setting or mute function. Only a toy not something you want to ware for some serious work.

sometimes I worry that I might forget to turn off my X-ray source when I am mucking around the lab. My sources (20 to 60kV tungsten target and no filter, just a beryllium window) don't come with a built-in audible alarm. This is the perfect solution. I can wear one and leave another on the bench and the one on the bench alarms when the tube is on. It is also good for quick checks for scattered x-rays or shielding leaks. Just some additional peace of mind.

***UPDATE***Upon seeing the below review, their customer service reached out to me for a replacement/refund. They were great to work with, so I'm updating the review to 3 stars.Pros:Easy to use for basic scansSmall and lightweightUSB-C charging portCons:Long delay in scanning (several seconds)Not very accurateMy big complaint with this device is that it isn't very accurate. I held mine to my smoke-detector, and the device read 0.1 usv/hr (normal) then jumped to 0.44 usv/hr, then back to 0.1 usv/hr. Even just standing still in an enclosed space, it will fluctuate from 0.09 to 0.19 with no reason. The manual says it is accurate within 25%, but I'm not getting results even close to that. It also takes more than 10 seconds sometimes to get a measurable result. I held my device to Uranium glass for a full 30 seconds, and it wasn't until I turned away that the meter spiked up to 0.55 before dropping back down immediately. I recommend spending a few bucks more for another model.
