by Xray at entry point to NZ i.e. UPS > Customs?

Have had 2 instances of gear OK before transit (1 from USA, 1 from UK) but
defective on arrival here.

NOT due to impact - both very well cushioned and in strong cartons.

Haven't been able to find out if Adani Systems gear is used here.

TIA

Never. Been in and out of the UK at least once a year fot the last 20 years and never had anything cooked. It's xray not magnetic fields.

tegretol - 2021-04-14 23:42:00

Well. From what I have read, Xray won't damage electronics but metal detectors can. Do you think they may have passed through a metal detector as well as Xray?

muppet_slayer - 2021-04-15 00:19:00

Eh? Why would they put a UPS thru a metal detector? Don't know that they even have them. Xrays detect metal.

No.

no - i have travelled in and out of both the US and the UK multiple times with my work lap top ....its never been fried....

well radiactive radiation kills electronics.. if you where alive when chernobil happened you could see the electronics robots fail quickly and films destroyed by radiation.
There is not as much radation as in chernobil up there in aircrafts but a lot more then you know . Thunderfoot showed it once on a trip with his giger counter in aircraft. So a hotspot could kill electronics. coincidence or a possible reason if it gets hit by a high radioactive spike . As i had stuff dead on arrival that worked before my self over the years.

Wouldn't all the avionics in the aircraft fail then? How about all the satellites and spacecraft? Wouldn't all their avionics fail?

I have never had electronic items cooked going to the UK and I have been to the UK more time than I can count. I have imported heaps of electronic items from overseas and never had a problem. I suspect there was a problem with the items you brought in. What were they?

duncb - 2021-04-15 18:44:00

intrade, you are getting confused between radiation and EMF pulse with reference to Chernobyl. EMF pulses can destroy electronics , but normal gamma radiation won't hurt normal consumer electronics.

pheonix - 2021-04-15 19:52:00

What leads you to believe that the equipment was FULLY operational prior to sending ??
Also... defined "cooked"... is there signs of physical damage / burn marks etc to the components of this equipment... did this "very well cushioned and in strong cartons. / packaging" include protection from static electricity.. Are the people who packed up and sent these items in the business of this sort of stuff.. e.g. packing and sending electronic equipment around the world ?

Hubby works for an aircraft repair company. He's both sent and received very delicate Avionics Electronics to and from many places world wide. He's never experienced such an issue and I'd guess if he botherd to ask the Avionics techs they'd laugh at the thought. There are MILLIONS of electronic items sent all over the place from manufacturers and citizens all the time. They all go through some sort of electronic scanning at the borders - if this was going to damage goods there'd be a LOT of unhappy shippers and manfacturers. It just doesn't happen. Any scanning machine or device used on such goods is of course designed to NOT damage them. Jeez.

I have had stuff through the airport xray machines 100's of times, as well as through the prison xray system 100s of times, and never had a failure of any electronics

Please tell us how you know that these devices were definitely working prior to being sent. Did YOU pack them at the sending end ? Or are you relying on someones word ?

i dont know but i would say aircraft would likely have shielding against this and we do not know what happened to flight mh 370 its all just theorie but one that could be . also emf norhern lights can nuke electronics. i dont know if it can nuke electronics that is not turned on ... its not a claim just a potential theorie.

i think xray machines cant generate enough to damage it but spikes from out of space who knows.
Also flights used to fly higher up then they do now if i recall. i always had terrible jetlag who knows from nuclear radiation back in the 1990s never had much jatlag since i did fly with the airbus A380

Which NZ airport has equipment to produce radioactive radiation?

Aircraft components have shielding against EMF, as do most electronics, however you cannot shield against radiation in an aircraft as it is too heavy. Shielding against gamma radiation requires an inch of lead or several metres of concrete.

All EMF shielding requires is a bit of aluminum foil, hence the tinfoil hat joke.

See here on faraday cages. They are used to shield against emf

High intensity radiation can damage electronics, drones and remote robots don't last long in places like Chernobyl and Fukishima. That is pretty radioactive, and with digital X-ray machines the dose is now lower than ever.

So do these digital x-ray machines contain a radioactive source then?

tegretol - 2021-04-19 10:03:00

Not in that sense, no. Huge difference in energy and penetration.

They don’t require a radio active source to produce ironising radiation. Both an X-ray machine and a nuclear bomb produce ironising radiation at different levels. Ironising radiation is when the radiation can react with matter and eject and electron from an atom- that’s what causes tissue damage.
A nuclear bomb produces gamma rays through nuclear fission. An X-ray machine makes x rays simply by heating a negative charged electrode - electrons are released off it and focused at an anode ( positive charged) those electrons released from the electrode collide with the atoms in the anode which makes an X-ray The level of exposure when getting an X-ray is pretty low - it’s focused and pretty short duration so shouldn’t have any lasting affects.
Then you come down to none ironising radiation which is lower frequency stuff you come across everyday it doesn’t have enough energy and a shorter wavelength to ironise completely but enough to excite electrons- which is how your microwave oven works. Exposure to higher levels can make you fell little tired etc very high levels can produce RF burns. On the high power transmission sites I work on we carry a device that warns us off excessive none ironising radiation. When rigging on the high power sites we wear what we call a RF suit to protect from prolonged exposure to none ironising radiation.
I,m an RF engineer so I understand the physics behind X-ray but nuclear science and natural occurring radiation I just can’t quite get my head around.

Would it be ionising, rather than ironising?

Yes. Spelling late at night has never been my strong point but you know what I mean

What is the common denominator in these 2 consignments of electronic equipment sent from two different countries and arriving at the same destination, and then testing faulty ?? the OP's and his / her destination and testing is common.
