Honestly,never heard about any report that guidance systems for Patriots causes cancer.

Maybe they have not been used long enough or maybe the irradiated population is too small to see a rise in cancer rates. But if neither of these is the cause, what is then so special about the Hawk radar to be the only one causing (lots of) cancers?

Almost 90% of the cases happened with maintenance personal,engineers and so on.There is one thing though,everybody was aware that radar installation could cause irradiation but how much nobody said.More than that,the manufacturers of the systems failed to warn ALL technicians (was too late) and they did not installed protective shielding around the tubes that caused pottential irradiation.As I read in an article , there are many kinds of switching tubes in radars systems and even if there are differences among them,they are all used to control the flow of electrons through the circuit. Now, let's be clear,it was common knowledge that such tubes could release radiation, even back in the 50s.It is also true that X-ray intensity falls off rapidly with distance, so if people were exposed even a foot or more distant, then the exposure levels would be much lower.Yet the long exposure caused cancer.
Now,before everyone jumps and say that it was faulty maintenance,I say that the installation DOES IRRADIATE! Wether you are one inch or one yard away.And these happened not only in the Dutch Army. US,Belgian,German Army alike.
It is clear now that it was a manufacturing negligence.Just think of the fact that when you go to dentist for an X-Ray they put a sort of lead apron on you in order to protect. The tubes in the radar system had NO PROTETCTIVE SHIELDS and they are like that today.I don't know if Romania have capability to mount such devices but if they don't , then I'm really sorry for the operators.
As I said in my previous post,I'm not pissed about the fact that they bought a defence system(quite outdated yet very usable),but the fact that they had to do their lessons and check the whole picture.But then again,on both sides there was a lot of money involved.And I am not talking only about the numbers presented in the contract.

well all can be corrected with some shielding...
I am curious about the radiation from the SA-2 radar systems

Definitely!
This will constitute the object of a future multi-million contract between Romanian Ministry of Defence and South African Army.

Getting over the lack of professionalism shown by the reporter,a fact remains.Shielding will happen when the pigs will fly.And they do not talk about the new aquisitions.Nope.

Minimal measures are not taken.What the military have to do?Strike?

Finally they got it right... EM radiation in RADARs is old stuff.. they just need to protect them self.. and the thing is unless they stay for long intervals in the Scaning area or tracking beam nothing much will happend.

Heh,yes,they should buy from their salaries some things they need.You missed the entire point.It was not about the EM emission - which indeed is known since 50's - is about what the ministry/govt. doing to protect these guys.
Better yet,I suggest you to take a job as radiolocator in the army.Pay is not good,besides,when you turn the switch on the station you are always prone to contamination.About not staying long around the switched on station tell that to the radiolocators.Next time when I will be home I will invite you to see something and hear some things.From such people.Around real installation,we can't get inside - I'm sure you will not want after you speak with these people.The whole thing is a gamble.There are books,entire manuals in the army (I read many of them from my father) , the fact remains : measures are not taken.And these measures are meant only to minimize the effects,not as a waterproof solution.In fact that's they complain about,but as usual,reporters screw the whole things up.

I don't need to talk about this wink.gif ..got my sources also... a cuz that was in Radiolocatie during the army ... Big ass P35 operator.. at a certain point he used to write in reverse faster with same speed as with normal writting.

man ..you keep forgeting that Romania is not Netherland;) ...Gov/MOD won't protect shit ... ever wink.gif

That was the guys were talking.Unfortunately journalists f*ed up the story as usual.They were complaining that even if there are clear indications what to do in such cases they are not respected.And not because they don't want.Is because who's supposing to ensure the materials don't give a f***. That was their problem.
I don't want to go into the modernisation problems now,is not the place and definitely they don't have the budget.Hence the HAWK sys aquisition.

X-rays? huh.gif
What would X-rays be doing in a radar system? You probably mean EM radiation in the radar X-band (frequency 8 to 12 GHz), which is used for short range guidance radar or even police radars. X-rays have frequencies significantly higher and are a totally different thing.

Unfortunately we do not know very well how EM radiation affects us, although it is clear that too much of it isn't healthy. People working in this enviroment lose hair in time, others their teeth and some even develop cancer. There are safety standards for mobile phones, for base stations, access points etc, etc. There should be some for radars too. But obviously somebody has to check they are respected and we all know how well regulations are respected in Romania.

Victor i think is all about the power of the transmiter.

And the Guidance Radar for V-75 is in Megawatt range.
From fas.org:
FAN SONG C/E
Fire Control & Tracking
Can track six targets simultaneously

# 1.0 Mw power
# Vert Ant BW 7.5x1.5deg
# Hort Ant BW 11.5x7.5
# Scan 15.5-17HZ
# PRF 828-1440 Search
# 1656-2880 Trk
# PW .4-1.2ms us
# 2-.9ms us

Victor,why don't you reply to all my post?Because that's what you should do.First ,document yourself regarding the issue,read my post ,and only after that put some relevant data in the discussion (I know,I know,I am not entitled to judge as you suggested me so kindly earlier).FYI:.I have said X-rays because this is something what people have contact with.They know less about radio waves than X-rays.But they don't have any idea how much alike these two are.Seems that there are a lot of people thinking that X-Ray are much more dangerous than EM ones.Guess what,they are not.
Did you attend all your physics class when in the highschool?Because across the EM spectrum radio waves, visible light, X-rays, and all the other parts of the electromagnetic spectrum are fundamentally the same thing.I thought you knew that.Sorry if I was wrong.Anytime,I can introduce you in this beautiful world:).Introduction only because I am no expert.That, in case you missed your XII grade physics classes.I still have the book ,you know?If you want a scan ,tell me.I'll do my best to scan the relevant paragraphs.

And from the same saga : http://www.jurnalul.ro/articol_36156/rache..._intrebari.html

Idiots have no idea that there are not the rockets irradiating.
Later edit : dragos,this could prove a very good strategical move.There won't be a referendum in The Netherlands where if Romania should join or not EU in January 1st 2007. Is a Second Chamber acknowledgement only. Actual government will rule at least until next year.In the spring they have to acknowledge wether Romania fullfiled their part of deal.Oooops.

edit : off topic remark deleted
