A Troxler 3440 moisture density gauge equipment which has radioactive materials has gone missing a month ago, the Department of Science andย Technology (DOST) said Monday night (September 17).
The Philippine Nuclear Research Institute (DOST-PNRI) has warned of its radioactive contents, saying those who may have the equipment should not tamper with in any way, much less open it.
A statement from the PNRI said the density gauge “was reported missing a month ago at around the area of the MWSS Compound storage facility in Bigte, Norzagaray, Bulacan.
Here’s the complete statement of the PNRI:ย
A moisture density gauge equipment containing radioactive materials wasย reported missing a month ago at around the area of the MWSS Compoundย storage facility in Bigte, Norzagaray, Bulacan.
According to the Department of Science and Technology-Philippine Nuclearย Research Institute (DOST-PNRI), the equipment was reported missing by aย licensee, which has reported the incident to the Norzagaray municipal policeย station.
DOST-PNRI is the the agency mandated to license and regulate theย use of radioactive materials in industry, medicine, academe, research, andย other applications.
DOST-PNRI has then notified the Philippine National Police (PNP) and the Office
of Civil Defense (OCD) of the incident and has requested for assistance in the search
and recovery of the missing equipment.
The missing equipment is a TROXLER 3440 moisture density gauge, whichย is used by the PNRI licensee, an industrial firm, for testing of soil, asphalt andย concrete materials. The equipment weighs around 41 kg, which is containedย in a transport “orange-colored” box measuring 30 x 14 x 17 inches. The gaugeย looks similar to the photos below:
The public is advised on the following:
— The moisture density gauge is fully shielded, and is safe as it is.ย However, the equipment is potentially dangerous as it containsย radioactive materials that emit high levels of ionizing radiation. Ifย found, do not open the unit or tamper with its housing to avoidย exposure to harmful radiation rays.
— Attached to the transport containment and on the equipment is theย radiation symbol that looks like below. If you see the radiationย symbol, keep away from the equipment.

— Those who may have seen, touched or have been near to theย equipment should immediately report to the nearest police station,ย and contact the DOST-PNRI as soon as possible through:

— Scrap metal dealers and buyers of used metal items are asked to beย on alert.
— Medical practitioners are advised of the possibility that patients mayย appear with symptoms of radiation exposure.
Further information will be provided as soon as it becomes available. (from DOST-PNRI)
