One of most challenging problems from applying the Black-Scholes model to financial derivatives, is reconciling the deviation between the expected and observed values. This study derives an extension of the Black-Scholes model and recovers the real drift of binary call options from their market prices. For space-dependent real drift, we obtain stable linearization and an integral equation. We also find that using market prices of options with different strike prices enables us to identify the term structure of the real drift. Results demonstrate that our new approach can confirm the existence of arbitrage opportunities in a binary option transaction.

A circuit was devised for removing the influence of Rn and Tn on an ionization chamber gas monitor for β rays. The circuit subtracted the current due to Rn and Tn from the gross current. A monitor installed the circuit canceled the concentration variation of Rn and Tn caused by ventilation condition. The background level of the gas monitor compensated the influence of Rn and Tn was reduced by 10%. The minimum detectable concentrations of the compensated monitor were lower than the legal concentration limits in exhaust gas of 8 radioisotopes used in life science research and nuclear medicine: 3H, 14C, 24Na, 51Cr, 67Ga, 75Se, , 89Sr, 99mTc, and 3 main radioisotopes discharged from the nuclear power plants: 85Kr , 41Ar and 133Xe.
