Insects and Locusts in fallout dust buckets

Insects and Locusts in fallout dust buckets

Insects and locusts can contaminate fallout dust buckets, especially in swarm or high concentrations of the insects. The strainer used during filtering will remove these from the sample but depending on how long the insect was in the bucket, the water may be further contaminated, making the processing of the sample more difficult, and in some cases the sample will have to be discarded.

Potential solutions are a mesh placed over the top of the bucket. Research into the impact of this has not been published yet, but the logic says that the dust will collect on the mesh and not land in the bucket. The mesh may also impact on the aerodynamics over the lip of the bucket causing more or less dust to be collected. Our initial assumption would be that more dust is collected in this situation.

Fallout Dust Monitoring and SANAS accreditation

DustWatch cc specialises in fallout dust monitoring and will be able to supply the fallout dust equipment, and laboratory equipment required to operate a fallout dust monitoring programme. We also provide training on site or in central location for people on fallout dust monitoring. SANAS accreditation for fallout dust monitoring is not feasible, especially when mines are in remote locations and doing the analysis of the samples in house. There is also no specific SANAS accreditation for just a fallout dust monitoring laboratory, so a laboratory that wants to have this accreditation must also qualify to do the other tests related to obtaining the SANAS accreditation.
