Talk:Radioactive scrap metal

Preventive detection and monitoring?
Is there any systematic attempt to monitor scrap metal at collection, shipping, warehousing, and usage locations, to detect radioactive contamination? Previously, monitoring was done only around a small number of large industrial or research facilities specifically dealing with radioactive material. There was discussion of widening the monitoring for radioactive materials, and this idea spread more widely after 2001, but have there been any significant changes as a result? The cost and practicality of small radioactivity detectors has improved dramatically over the past century, but has this resulted in more widespread deployment of such devices, like the proliferation of miniaturized video cameras?

Smoke detector recycling
Ionization-type smoke detectors typically use a small amount of radioactive americium. In theory, obsolete/defectve/damaged devices are supposed to be returned to the original manufacturer for disposal, but this definitely is not happening in the US. Has radioactive contamination from old smoke detectors ever become an issue of concern, or is it a negligible problem? Also, some lightning rods and antistatic devices used radioactivity in their operation. As these items enter the waste stream, are they considered problematic or not?

 * Yes, we had an incident here. Tangentially mentioned in discussions that a church had one, and it was removed in the 1990s during routine roof maintenance and replaced with a more effective conductor.
 * Supposedly it was sent back to the UK with other radioactive materials in a lead pig, under guard because it measured an absolutely astounding 40MBq suggesting a lot more contamination on the surface. 78.111.195.1 (talk) 07:54, 9 March 2023 (UTC)

Possible 2023 incident?
Hi, contacted authorities as found potential contamination in some steel pins sold with a children's art kit. One pin actually registered high enough that my counter showed a warning light after 40 minutes of exposure. Any ideas? These things seem to be quite common and there was a similar event a few years back with 5G "pendants" that contained thorium and other radionuclides that made the news yet not mentioned here. 78.111.195.1 (talk) 20:51, 5 March 2023 (UTC)
