What context is wikipedia missing from this investigation section about cs-137 that makes you think that there is more out there?

The Indonesian government followed up on the report, with a joint team membered by the Ministry of Environment, Ministry of Trade, National Energy Regulatory Agency, National Research and Innovation Agency, Mobile Brigade Corps, and local government officials[20] conducting a search in the Cikande Modern Industrial Area and discovering the presence of Cs-137 radiation.[21] The government has declared a special incident for Cs-137 radionuclide radiation in the Cikande Modern Industrial Area. The radioactive substance has reportedly contaminated nine people.[22] On October 3, Indonesian authorities announced that the radioactive material originated from a metal scrapyard in the Modern Cikande industrial park near Jakarta, and that the nine contaminated local people and workers have undergone special medical treatment.

The scrapyard factory is considered to be the epicenter of the contamination; the number of contaminated areas throughout the industrial park, which was initially thought to be six, was later determined to be ten (two of which have been decontaminated).[23] Investigators ascertained that the caesium-137 entered the domestic supply chain through a stainless steel smelter operated by PT Peter Metal Technology in Cikande, Banten province; it has been declared the local source of contamination and shut down. Given that the scrapyard and the seafood processing plant were less than 2 km apart, the working hypothesis is that the cesium-137 was airborne, or carried by the wind.[24]

On 14 October 2025, the Ministry of Environment and Ministry of Trade issued a temporary ban of importation of iron and metal scraps into Indonesia.[25]

A ring of iron thieves also played a role in dispersing the radioactive contamination. On 10 December 2025, police uncovered a group that had been stealing iron scraps from PT Peter Metal Technology iron waste storage over several months. Although only about 200 kg of scraps were stolen, compared with 1.136 metric tons of contaminated materials overall in storage, the radioactive contamination from the stolen iron was inadvertently dispersed by the ring through their clandestine network, so far reaching Serang Regency.[26]
