परिवहन के लिए A1/A2 और package type

Add a nuclide

सामग्री का रूप

Package की सामग्री

पहले से भरा उदाहरण — Ir-192 0.8 TBq special form (industrial radiography source). इसे हटाएँ और अपनी सामग्री जोड़ें.

  • Ir-192 · 0.8 TBq · special form
Type A packageΣ A/A1·A2 = 0.8 · UN 3332
What it means
Activity A1 (special form) / A2 (अन्य) से अधिक नहीं — सामान्य परिवहन स्थितियों (drop, stacking, penetration, water spray) के लिए परीक्षित Type A packaging पर्याप्त है (SSR-6 paras 429–430, 634–649).

Type A (para 430): Σ B(i)/A1(i) + Σ C(j)/A2(j) ≤ 1excepted (Table 4): Σ A/(10⁻³·A1 | 10⁻³·A2 | 10⁻⁴·A2 liquids) ≤ 1हवाई Type B (para 433): special form ≤ min(3000·A1, 10⁵·A2), अन्य ≤ 3000·A2.
  • Special form केवल वैध special form certificate वाली सामग्री पर लागू (SSR-6 paras 239, 602–603; sealed source certificate) — अन्यथा «अन्य रूप» (A2) चुनें.
  • Fissile material, uranium hexafluoride, LSA/SCO (industrial packages IP-1/2/3) और dose-rate/TI सीमाएँ शामिल नहीं — इन्हें अलग से जाँचें.

Kvant के transport packaging sets (УКТ)

Operating manuals से निर्माता सीमाएँ: हर УКТ प्रति nuclide अधिकतम min(A1/A2, shielding limit) ले जाता है. हरा = उपयुक्त, पीला = set की सीमा से अधिक, ग्रे = इस set में nuclide शामिल नहीं.

सीमाएँ निर्माता के operating manuals से हैं (स्रोत डेटा में revision दर्शित); शिपिंग का निर्णय विशिष्ट set के certificate और consignor की radiation safety service द्वारा लिया जाता है.

Package type by A1/A2

What A1 and A2 are

A1 and A2 are the basic radionuclide values for transport (IAEA SSR-6 Table 2; RF НП-053-16 Annex 1 Table 1 carries identical values). A1 is the Type A package content limit for special form radioactive material (a sealed source with a special form certificate); A2 applies to material in any other form and is never larger than A1 because it also accounts for internal exposure if the contents disperse.

The calculator takes the activity on the shipping date (passport value or decayed by half-life), divides it by A1 or A2 and applies the mixture rule of SSR-6 para. 430 to decide: excepted package (Table 4), Type A (sum of fractions ≤ 1) or Type B(U)/B(M), which needs a design approval certificate. For air transport the Type C threshold of para. 433 is checked.

Package types for radioactive material

Excepted packages hold fractions of A1/A2 (10⁻³ for solids, 10⁻⁴ for liquids) with minimal requirements. Type A packages withstand normal conditions of transport — 1.2 m drop, stacking, penetration, water spray — and are limited to A1/A2. Type B(U)/B(M) packages carry activities above A1/A2, survive accident conditions (9 m drop, punch, 800 °C fire for 30 min, immersion) and require a competent-authority certificate. Type C is for air transport of very large activities. Industrial packages IP-1/2/3 are for low specific activity material and surface contaminated objects and are outside this calculator.

Kvant УКТ packaging sets and loading limits

The УКТIА-65, УКТIА-85 and УКТIIА model 940 sets are Type A packagings; УКТIВ-5М is Type B(U). The loading limit of a given set is the lower of the A1/A2 regulatory value and the shielding limit: for Ir-192 and Se-75 in УКТIА-65 it equals A1, while for Co-60 and Cs-137 it is tens of times lower because of the surface dose rate. The calculator shows which sets accept the entered contents according to the operating manuals.

SSR-6 (Rev. 2) 2025 revised A1/A2 for 242 nuclides (Am-241, Cs-137 and Sr-90 among them); it is not yet adopted in НП-053-16, ADR or IMDG and is offered for reference only.
