We can use the formula for the half-life of radioactive material to get its value. {eq}N=N_{0}(\frac{1}{2})^{\frac{t}{t_{1/2}}} {/eq} Where, {eq}N {/eq} is the amount after decay, {eq}N_{0} {/eq} is the initial
The half-life of a radioactive isotope is the time it takes for a quantity of the isotopes to be reduced to half its initial mass. Starting with 110 grams of radioactive isotopes, how much will be left after 6 half-liv...
Presently, the effective half-life forCs deposition due to radioactive decay and other environmental factors is 4.7years. The estimation suggests that approximately 42years from 2011 are required to reduce the atmosphericCs deposition to a state similar to that before the accident. The currentSr ...
1. Understand the Concept of Half-Life: The half-life (t_half) of a radioactive element is the time required for half of the radioactive atoms to decay. In this case, t_half = 6.931 days. 2. Determine the Remaining Fraction: We want to find out after how many days (t) only ...

After a few months, the dispersed 131I in the environment was almost completely diminished owing to its short half-life, and further dispersion from the FDNPP did not occur. Furthermore, as the FDNPP accident occurred in March, most of the agricultural activity was not initiated, so direct ...
where kD is a drug-induced effect, Ctumor is the estimated concentration in the tumor compartment (taking into account radioactive decay), EMAX is the maximal drug induced effect of [177Lu]Lu-PSMA-I&T on PSA, EC50 is the [177Lu]Lu-PSMA-I&T concentration at which half of the maximum...
(Fig.4), making it a double-peaked SESN, although the rising part of the first peak is missing. The phase I light curve could be explained by the56Ni radioactive decay as in normal SNe Ic (see section ‘The energy source of the SN luminosity’ and the discussion below). The phase ...
This is because long-lived radiocesium (half-life is about 2 years for 134Cs and 30 years for 137Cs) contributed to the ra- diation dose rate after short-lived radioiodine 131I decayed quickly (half-life is about 8 days). The decay rates are different at different places. For ex- ...
The 33P beta-emission in the plant extracts and percolates were measured by liquid scintillation counting (TRI-CARB 2500 TR, Liquid scintillation analyzer, Packard Instruments, Meriden, CT, USA). The counts were corrected for radioactive decay and referred to the starting date of the labeling ...
