“…The density of the material and consequently the high atomic number are a crucial factor in the attenuation of the muon particles. Previous studies have shown that muons are more penetrability than other charge particles (Bonal et al, 2016(Bonal et al, , 2015Borozdin et al, 2003;Morris et al, 2013). Furthermore, it was demonstrated that high-Z materials can be located and detected using muography by cosmic-ray muons (Priedhorsky et al, 2003).…”

The absorption of cosmic ray muons was experimentally demonstrated using the telescope which was proposed in our previous work as a portable detector for high-density materials. The complexity of the muon interaction has pushed researchers to use the simulation program (GEANT) that recently showed some discrepancies with observations at high energy but did not describe the attenuation of all muon spectrum. In this study, the absorption/ attenuation coefficients for different elements, namely lead (Pb), copper (Cu), zinc (Zn) and aluminum (Al) were experimentally determined. The count-rate graphs obtained verified the familiar behavior of the absorbers, which led to the determination of the exact transition depth of the metals and the results were consistent with the properties of the metals in other previous works. The attenuation of cosmic muon in lead was very high in comparison with other metals; therefore, lead can be very easily detected by muon absorption. Our results indicate that the larger the atomic weight of the absorber, the higher the ability of the muon absorber. The determined coefficients reported by this study will be useful for future work for muon tomography and detection techniques.

“…These particles are free rays that exist everywhere. Muon rays have already been proposed as one of the rays used for radiography (Bogdanov et al, 2006;Bonal et al, 2016;Bonal, Preston, & Dorsey, 2015;Procureur, 2017).…”

“…The muon, with mass 200 times the mass of the electron and generated in the atmosphere by the incoming protons from space, have high penetration ability. They arrived at the Earth's surface with high energies up to 100 TeV that enable them to penetrate rocks about 100 m or a few kilometers thick (Bogdanov et al 2006;Bonal et al 2016Bonal et al , 2015. Therefore, muons as other rays protons and gamma rays, can be used in radiography (Procureur 2017).…”

“…Therefore, muons as other rays protons and gamma rays, can be used in radiography (Procureur 2017). The use of muon in radiography is called muography (Bonal et al 2016;Borozdin et al 2003). The detection of metals is one of the important applications and essential for muography.…”

“…Since radiation length drops rapidly with atomic number, in traveling 10 cm a 3 GeV muon will scatter, on the average, 2.3 mrad in water, 11 mrad in iron, and 20 mrad in lead (Priedhorsky et al 2004). Comparing the small amount of deflection in lead with the high range of energy of the incident muons, the design of such apparatus for the material detection is difficult and expensive especially when high technology is used to increase the angular resolution (Bonal et al 2016). Therefore, no work has considered the cost effectiveness and portability in designing a muon telescope for metals detection yet.…”

Muons produced in the atmosphere by cosmic rays are preferred over gamma rays, X-rays and fast protons for the detection of metals in the study of radiography. An alternative method for metals detection involving portable and relatively cheap Geiger-Muller counters are proposed. The objective of this study was to investigate the validity of using a handmade muon telescope with a small solid angle for the detection of muons inside the metals. This experiment was carried out at Universiti Kebangsaan Malaysia, Bangi (101.78º E, 2.92º N and elevation 30 m). Measurement of muons was conducted in the vertical direction using 1 set of muon telescopes (MT) consisting of coaxial Geiger-Muller (GM) counters. Different metals-lead (Pb), zinc (Zn) and aluminium (Al)-were used as absorbers with different thickness to observe its influence on the count rate of muons. The efficiency of the experimental setup was evaluated using statistical methods and by obtaining sufficient number of muon detection events to describe the physics of the muon interaction with the metals. Based on the Rossi curve obtained for each metal, the transition point was estimated as follows: 1.5 cm for Pb, 4.0 cm for Zn, and 9.0 cm for Al. The results showed that the proposed alternative setup was adequate for detecting muons and therefore have the potential to be further developed.
