First Manchester CN94UA Scania Omnicity 12018. (YN05 GYW) in First barbie livery, of course unbranded as the last three of the batch were for more 'flexibility' in their route allocations.. if you'll pardon the pun!

Intercités 12018 uit Amiens komt aan behoorlijke snelheid het kopstation binnen gereden. Dankzij een efficiënte veiligheidsuitrusting in Frankrijk kan de trein zonder nodeloos te slenteren vlot het perron bereiken. Iets wat erg ongewoon oogt wanneer men Belgische situaties gewoon is... 09/03/2017

personally, i think most anything over 3 cylinders is simply over engineered for a motorbike (not that i wouldn't love to stomp around on one of today's manic 4's—or yesterday's high strung sixes... i just wouldn't want to be responsible for keeping that many moving parts "happy" for any extended period of time. )
that said, i really liked this build. i found it easy to stand there, squinting my eyes, imagining riding tonup through high prairies in a brown leather jacket, replete with goggles and trailing silk scarf. (in the meantime, i'm glad to stick with my dainty machines in town).
another spy shot, captured during setup at the one motorcycle show.

Radioactive lenses -- group shot:
(a bit drab, not a very colorful group)
These lenses exhibit low-level radioactivity, probably caused by Thorium Oxide added to the glass to enhance its optical properties.

During the shot, the level of gamma radiation measured at the camera (about 0.5 meter above the lenses) was about 4-5x normal background, as measured with a Ludlum 44-2 NaI scintillation probe. One meter away, the level dropped to about 2x normal. (Ludlum 2221 settings: HV=775V, threshold(LLD)=10mV, background about 1900 CPM).

1) Surface (near contact) readings with geiger counter
. . --------------------------------------------------------------------
These are the typical readings where the Geiger Mueller tube is pressed up as close to the front or rear glass as possible.
Ludlum Model 2221 Scaler/ratemeter, with Ludlum 44-9 Pancake GM probe
Settings: High Voltage = 900V, Threshold (LLD) = 55mV
The 4 readings on each row are "F=r1/r2 R=r3/r4 CPM [x%]"
- r1 = close to front
- r2 = close to front with plastic cap (little/no alpha, some beta, most gamma)
- r3 = close to rear
- r4 = close to rear with plastic cap (little/no alpha, some beta, most gamma)
- x% = Max(r1,r3)-background / same value for Pentax 50/1.4 S-M-C Takumar
Lens caps off, focus at infinity, aperture fully open (may not affect some lenses)
Each reading was a 10 minute average.
Plastic cap off - background level was about 28CPM (26-30) - from 2x10 min averages.
Plastic cap on - background level was about 27CPM (25-29) - from 4x10 min averages.

2) Gamma counts 100mm away from side of lens
. ---------------------------------------------------------------
These readings should give a better indication of how much exposure you'd get farther away from the lens.
Ludlum Model 2221 Scaler/Ratemeter, with Ludlum 44-10 "high energy" gamma scintillation probe (2" x 2" NaI)
Settings: High Voltage = 850V (middle of 500v-1200v range), Threshold (discriminator) = 10mV. These settings gave a background reading of about 4400 CPM, which is near the minimum that this probe is supposed to read for the background. I wonder if the NaI crystal is degraded?
Method: The probe was placed horizontally on a table, with a small amount of lead shielding near the crystal. This reduced the background reading to about 1500cpm. The lens being measured was placed with the "hotter" end (front or back) downward, at the same level as the bottom of the probe. The lens was wide open (if possible), focused at infinity (if possible), and had both front and rear caps on (correct caps, when available). A 10 minute run with the 2221 scaler was done, and compared to 10 minute runs with no lens (background).
In the table, the "xxx CPM", value is xxx = (C-B)/10, where C is the 10-minute count 100mm away from the lens, and B is the 10-minute (shielded) background count. The "[ppp%] is the xxx value for this lens compared to the xxx value for the 50mm f/1.4 S-M-C Takumar, computed as a percent.
