I ount away from 131 I for the surface to have evaluation on thyroid malignant tumors instances stated throughout the PBLS and you will FSS. The knowledge throughout the ground data into the Dining tables 1 and you may 2 from the enhance demonstrate that the fresh new levels of 134 Cs and you can 137 Cs is actually perfectly coordinated together. While doing so, the new levels of 131 I frequently integrate a few age out of additional sources due to the multiplicity regarding explosions that taken place at Fukushima Dai-ichi NPP twenty eight .
So you’re able to appraise the fresh new cousin requirement for 131 We about full radiological disease inside the Fukushima, we determine the newest provided immersed serving of every big radioactive function utilized in crushed in the 1st 12 months ranging from , due to the small 1 / 2 of-lifetime (8.02 days) regarding 131 We. Which investigations is supposed only for the fresh exterior amount. The integrated engrossed serving away from 131 We is focused on that-third to your February 15 presumption and something-fifth to possess February 20 presumption when compared to the sum of men and women away from 134 Cs and you may 137 Cs, the spot where the quantity of 137 Cs is step one.2 times bigger than regarding 134 Cs. In most municipalities, the latest contribution from 131 I concerns you to-third to 1-fifth of this of the Cs isotopes. It ought to be indexed, not, one to particular municipalities for example Iwaki provides big benefits from 131 We than others. When we were to make ount off 131 We is actually comparable to rays amount considering the Cs isotopes during the Iwaki. Are you aware that internal dose, we talk about the fresh relationship between your thyroid gland cancer times together with quantities of 131 We during the municipalities. Indeed, the interior doses estimated on the UNSCEAR declaration are correlated which have brand new amounts of 131 We from inside the ground 31,29 . We need to recall, although not, the internal thyroid dosage would depend mainly towards the set you to a child visited in early days of brand new crash and you may plus towards your weight-loss practice adopting the crash considering the small life time (8.02 days) out of 131 I and its own particular coverage paths, particularly inhalation and you can consumption.
As well as the size of air-dose rates and you may radioactivity from inside the ground during the Fukushima prefecture performed for the , you can find airborne light measurements playing with helicopters flying from the an altitude around 150
To the thyroid cancers and you can rays dosimetry pointers talked about more than in give, we have now proceed to examine the relationship within stated thyroid malignant tumors times as well as the projected dosage off light
3 hundred meters. The latest airborne proportions are performed sometimes but still consistently day jak sprawdzić, kto cię lubi w loveaholics bez płacenia thirty-two . The brand new research of your own show mentioned on the ground twenty-eight facing those of airborne dimensions suggests that light levels continued in order to decline pursuing the floor survey is held. We do the studies from airborne specifications from and evaluate her or him which have that from the air-serving pricing mentioned on to the floor. In the most common places, the new costs advertised by the airborne sampling program act like those individuals in the ground questionnaire. In some instances, although not, improvement reaches about something away from several in guidelines.
Approach
According to the issues mentioned in the previous sections, more complete and you will reliable information for usage while the replacements on thyroid gland dosage certainly are the heavens-dosage pricing plus the levels of radioactive content inside surface corrected so you’re able to . We understand new malignant tumors times for every single town therefore the sky dosage information by taking mediocre over of many environmental radiological specifications made within the area. There are, not, of numerous municipalities the spot where the number of cancer tumors cases was zero otherwise short because the number of students inside the the city worried are quick.
