Just another variant of my OCD fixatedly preoccupational absorbed and engrossed collecting habits.
btw – all of the following are generally readily available – I just picked these up as I came across them
2" Uranium Glass Sphere - 556 CPM Uranium Glass
2% Thoriated Tungsten TIG Electrodes - 684 CPM Thorium Containing Welding Rod (1990s)
Uranium Ore - 1935 CPM
Uranium Glass Tubing - 3285 CPM
Luminescent Radium Watch Hands - 17,580 CPM Radium Girls
Coleman Thorium Lantern Mantles - 30,040 CPM Incandescent Gas Lantern Mantles
Fiesta Ware Saucer w Uranium Pigment - 47,520 CPM - Fiesta Ware (ca. 1930s)
Depleted Uranium U238 - 49,370 CPM Uranium and Depleted Uranium
INSPECTOR + RADATION ALERT Specifications
Detector:
Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.75 in.).
Energy Sensitivity:
Detects Alpha down to 2 MeV
Detects Beta down to .16 MeV Typical detection efficiency at 1 MeV is approx. 25%
Detects Gamma down to 10 KeV through the end window. 3340 CPM/mR/hr (Cs137) Smallest detectable level for I125 is .02 µCi at contact
Operating Range:
mR/hr - .001 (1µR) to 100
CPM - 0 to 350,000
µSv/hr - .01 to 1000
CPS - 0 to 5000
Total/ Timer - 1 to 9,999,000 counts
Accuracy:
mR/hr ±10% typical (NIST), ±15% max - 0 to 100
µSv/hr ±10% typical (NIST), ±15% max - .01 - 1000
CPM ±10% typical (NIST), ±15% max - 0 to 350,000

I would leave your sample in the small pleated plastic envelope just as it is - I opened mine mistakenly thinking the U238 bits were in an ampule wrapped within the smaller plastic padding within the envelope - but I found the bits weren't further contained at all - and the lesson learned is the envelope itself contains the argon gas and they just hid the damn bits from view within the certainly unnecessarily inner wrapping.
