### Step-by-Step Solution:

1. **Understanding Flame Colors**: Different elements produce characteristic colors when burned. This is due to the excitation of electrons in the atoms, which release energy in the form of light when they return to their ground state.

2. **Identifying Common Elements**: The most common elements used in fireworks that produce colored flames include:
- Sodium (Na): Produces a yellow flame.
- Potassium (K): Produces a lilac or light purple flame.
- Barium (Ba): Produces a green flame.
- Calcium (Ca): Produces an orange-red flame.

3. **Focusing on Green Flame**: Since the question specifies that the fireworks produce a green flame, we need to identify which of the common elements produces this color. From our list, we can see that:
- Barium (Ba) is known to produce a green flame.

4. **Conclusion**: Therefore, the radical that may be present in the fireworks to produce a green flame is **Barium (Ba)**.

### Final Answer:
The radical that may be present in the fireworks giving a green flame is **Barium (Ba)**.
