Nuclear radiation detectorTen thousand units were sold overnight, the core geiger tube rose from $70 to nearly $200 for three days, and a small tube stuck in the lifeline of the entire industry。
How can geiger detect radiation
Inert gases, such as argon gas, are filled inside the gegger miller count tube, and positive and negative ion pairs of alpha, beta or gamma rays are generated in the tube as they pass through the wall. Following high working voltage, each pair of ion is amplified by an avalanche into an equivalent electrical pulse, with a dose rate for the recording of pulses in a unit time. This tube remains the core detection element of the household detector until 1908, when geiger was invented。
Without this tube, the geiger counter won't turn up. It turns invisible ionizing radiation into a measurable electrical pulse, giving the chips to calculate the value of the microsevere per hour and beeping alarms beyond the set threshold. In essence, the whole device was struck several times in the count。
Disassemble the core chip
A geiger counter was removed by the b station owner, fire1tech, and the main control chip had been polished by the plant, approximately atmel series, lifting the chip tps 61040 to 5v to power the single machine, with two sot chips and passive components. The eeworld removed fs 2011 was controlled by tti msp430f149 and boosted by adi max641acsa, the geiger tube model j305 beta gamma。
Vibrator master decomposed foloque at a high end with a radiation surveyer, asm990, controlled by microchip atmega128l, a bitter with adi ds 1844-100 and the rest with electric resistance. Whether the brand is changed or changed, the core is always a gel tube, the chip is only for pulses and drive screens, and the entire tube is empty。
40% of the cost of a pipe
According to eeworld decomposition data, the purchase price of a geiger tube in a geiger counter with a sales price of $400 was approximately $100, at a direct cost of one quarter. CurrentElectricianThe gel tube on the platform rose from more than 70 to nearly $200 three days ago, with a small number of spot sellers raising prices. The tube is mainly used for nuclear physics, medicine, particle physics and industrial testing, and there are virtually no individual buyers, and the name of the brand is almost invisible to the electrician。
The cheapest option offered by industry is the replacement of a gill tube with a digital tube at a cost of up to a few dozen pieces, but with a big question mark on the accuracy and professionalism of testing. The average consumer spends dozens of dollars on a digital tube to show a number, and the radiation value can't be judged at all, which is blind。
Shenzhen tsang creek's energy anxiety
The fnirsi network shows that the company has a combined production base of about 30,000 square metres in shenzhen and zhejiang tsai creek, with an annual capacity of over 5 million. However, the electrician's flagship shop has changed to a down payment model, with the final payment only on 1 september, and short-term deliveries clearly fall short of breaking orders. In the country, which is also a portable radiation detector, the wealthy and belett manufacturers are being cut off。
A large group of people in shenzhen e-communicators sniffed out commercial opportunities, looked around the world for geiger and tried to crack programmes to develop similar products. Everyone in the group says they're a source factory, and practically none. Both distributors of metaware and terminal plants want a piece, and the surge in short-term demand creates a serious imbalance between supply and demand。
The expert says there's nothing to detect
Wei honglin, an expert in nuclear radiation detection technology, stated that the cost of the geiger tube was at least $100 and that it would be very difficult to sell products at such a low price. With high operational thresholds, sample radiation values are largely invisible in the range of instrument fluctuations, and the general population has no expertise to accumulate, and it is difficult to detect differences with such instruments and not to be deceived by the figures on the screen。
Household detectors can only detect external exposure, and internal radioactive content in cosmetics and food products cannot be detected at all. Moreover, the instrument was re-calibrated six months to one year, and the subjects had to be selected very carefully, and the so-called life-guard was actually a little witch。
Can a tube carry a fire chip
This is a reminiscent of the lost capacity, chip shortages, and doubling of prices in 2020 when the gun gets hot. Geiger tube demand broke out, atmel, ti, microchip's primary control chip and adi's pressurized chip, electrocutor chips were all targeted, distributors went crazy to find cash, and a batch of metaware was brought hot for short periods。
Japan's nuclear contamination of water has not yet reached china, and anxiety and fear have spread on a massive scale, fearing radiation for cancer and hoarding anything that lives. Ten thousand units a day rely on money to buy peace, while others are simply curious to measure the surroundings. However, the supply of the geiger tube is limited and the price has doubled, and the rotation can last for how long, and the key caretakers can expand production rapidly。
Do you think the price of the geiger tube will continue to rise? The comment area is welcome to talk, and if it is useful, send it to friends。
