I just read about Amsterdam commemorating 25th anniversary of Bijlmer disaster, october 4th 1992 ;i didn't know depleted uranium is used for balancing passenger airplanes ?!

; i used to add lead in my models, still toxic.
from Wikipedia about this crash bellow;
"Health issues[edit]
Mental health care was available after the crash to all affected residents and service personnel. After about a year, however, many residents and service personnel began approaching doctors with physical health complaints, which the affected patients blamed on the El Al crash. Insomnia, chronic respiratory infections, general pain and discomfort, impotence, flatulence, and bowel complaints were all reported.
67% of the affected patients were found to be infected with Mycoplasma, and suffered from symptoms similar to the Gulf War Syndrome or Chronic Fatigue Syndrome-like symptoms.
Dutch officials from government departments of transport and of public health asserted that at the time of the crash it was understood that there were no health risks from any cargo on the aircraft; Els Borst, minister of public health, stated that "geen extreem giftige, zeer gevaarlijke of radioactieve stoffen" ("no extremely toxic, very dangerous, or radioactive materials") had been on board.
However, in October 1993, the nuclear energy research foundation Laka reported that the tail contained 282 kilograms (622 lb) of depleted uranium as trim weight, as did all Boeing 747s at the time; this was not known during the rescue and recovery process.[16][17]It was suggested that studies be undertaken on the symptoms of the affected survivors and service personnel, but for several years these suggestions were ignored on the basis that there was no practical reason to believe in any link between the health complaints of the survivors and the Bijlmer crash site. In 1997, however, an expert testified in the Israeli parliament that dangerous products would have been released during combustion of the depleted uranium in the tail of the Boeing 747.
The first studies on the symptoms reported by survivors, performed by the Academisch Medisch Centrum, began in May 1998. The AMC eventually concluded that up to a dozen cases of auto-immune disorders among the survivors could be directly attributed to the crash, and health notices were distributed to doctors throughout the Netherlands requesting that extra attention be paid to symptoms of auto-immune disorder, particularly if the patient had a link with the Bijlmer crash site. Another study, performed by the Rijks Instituut voor Volksgezondheid en Milieuhygiene, concluded that, although toxic products had been released at the time of the crash, the added risks of cancer were small, approximately one or two additional cases per ten thousand exposed persons. The RIVM also concluded that the chances of uranium poisoning were minimal.
